Flavonoids and hair health -
Flavonoids, especially citrus flavonoids, may also increase the effectiveness of vitamin C. A small, preliminary trial in Germany, conducted by the Department of Dermatology at the Saarland University Hospital and published in the Journal of the American Academy of Dermatology , gave subjects with progressive pigmented purpura a chronic bruising disorder 1, milligrams per day of vitamin C and milligrams per day of the flavonoid rutin.
After four weeks, noticeable bruising was no longer apparent and did not recur in the three-month period after treatment was stopped. In one study published in Oral Surgery, Oral Medicine, and Oral Pathology , people with herpes infections received either a placebo or milligrams of vitamin C plus milligrams of flavonoids, each taken three to five times per day.
Compared with the placebo, vitamin C and flavonoids reduced the duration of cold sore symptoms by 57 percent. This shows bioflavonoids can naturally treat herpes and cold sores. The bioflavonoid quercetin — found in onion, citrus fruit, pineapple and buckwheat — is commonly used in the treatment of allergies.
Quercetin is a natural antihistamine and an anti-inflammatory that can lower the effects of seasonal allergy symptoms and food allergies, as well as asthma and skin reactions. It can help stabilize the release of histamines from certain immune cells, which results in decreased allergy symptoms like coughs, watery eyes, runny noses, hives and indigestion.
Research published in the Iran Journal of Allergy, Asthma, and Immunology shows that quercetin fights allergies as well as some prescription medications, all with little to no side effects. Many studies have shown that consumption of fruit, vegetables, tea and wine may protect against stroke.
The major risk factor for stroke is hypertension or high blood pressure. Another study published in the American Journal of Clinical Nutrition found that certain flavonoids like anthocyanins and some flavone and flavanol compounds may contribute to the prevention of hypertension.
This is why fruits and veggies high in bioflavonoids are included in diabetic diet plans. While more research is needed to confirm the anti-cancer effects of flavonoids, the preliminary work provides plenty of promise.
For example, certain bioflavonoids have been shown to potentially stop cancer cells from multiplying. Citrus bioflavonoids in particular have been studied for their effects on the metabolism and metabolic health. Flavonoids showcase anti-inflammatory effects thanks to their antioxidative status.
Given their anti-inflammatory and antioxidant properties, bioflavonoids naturally can boost immune health. The consumption of flavonoid-rich fruits and vegetables may therefore improve immune function.
These compounds are excellent at promoting longevity and overall health thanks to all their beneficial properties.
In addition to fighting aging by improving immune health and supporting so many bodily functions, flavonoids also protect skin health and combat signs of aging.
For instance, bioflavonoids show promise in preventing and treating certain skin diseases, such as vitiligo, psoriasis, acne and atopic dermatitis. Consuming fresh fruits, vegetables and herbs is without a doubt the best way to take in bioflavonoids.
Chocolate, tea and wine in moderation can also be healthy sources, as are some spices, nuts, dry beans and seeds. Flavonoids are often concentrated in the skins and outer portions of fruits and vegetables so these portions of the foods are excellent to consume.
Fresh fruit, especially citrus fruits , berries and tree fruits, are awesome choices when it comes to bioflavonoids. Strawberries , grapes, apples, cranberries and blackberries are high in the bioflavonoid ellagic acid.
Citrus fruits like lemons, limes, oranges, tangerines and grapefruits are rich in citrus bioflavonoids. Apples, peaches and plums are rich in the flavonoid flavanol.
Feel free to eat any and all vegetables, particularly green and red ones, to obtain your daily dose flavonoids. Broccoli , kale, onions red, yellow and spring , red and hot peppers, rutabaga, spinach, and watercress are some of the heavy hitters when it comes to flavonoids.
Red and green onions are especially high in quercetin. Artichokes and celery are high in the flavones, while okra and broccoli are high in flavonols.
Fresh oregano, parsley, peppermint and thyme are high in the flavonoid known as flavone. Cinnamon is a great choice when it comes to spices as well. Black, green and red rooibos tea are great beverage choices to up your flavonoid intakes.
These tea varieties have all been shown to be high in catechins and flavonols. Moringa tea is also a great choice. Flavanols are the main type of flavonoid found in pure cocoa as well as chocolate made from cocoa and cocoa butter.
Both red and white wine contain flavonoids, but red wine has higher levels since fermentation occurs in the presence of grape skins, the source of significant amounts of flavonoids. If you drink already, then wine, specifically red wine in moderation, can be a healthy choice.
Moderation means not more than one glass per day for women and not more than two glasses per day for men. The soybean is particularly high in bioflavonoids, especially isoflavones like genistein and daidzein.
Dark beans — such as black beans and kidney beans, as well as garbanzo, pinto and fava beans — are rich in bioflavonoids. When it comes to nuts, pecans, walnuts, pistachios and cashews are great choices. You might be wondering what the difference is between bioflavonoids and carotenoids.
This is understandable, since both come from similar sources and have similar benefits. There are no consistent side effects that have been linked with bioflavonoids except for supplemental catechin, which can occasionally cause fever and anemic symptoms from breakdown of red blood cells and hives.
High intakes of dietary flavonoids are generally regarded as safe. However, extra large amounts of supplemental bioflavonoids, which might be harmful to your health rather than helpful, are not recommended.
While obtaining bioflavonoids from food sources is very safe, getting you bioflavonoids from supplements is more controversial. Bioflavonoid supplements may affect the action of anticoagulants and increase the toxicity of a wide range of drugs when taken concurrently. Talk to your doctor before supplementing with bioflavonoids if you have any ongoing health concerns and currently take other medications.

One of Flsvonoids most heslth features of hair healthh the specific growth Flavonoidx consisting of three distinct phases—anagen, catagen, and telogen Flaonoids 78 ]. Hair growth and new hair induction are an tightly regulated by the hair cycle [ 7 ].
Exposure of hair to internal and external ahd, stress, pollution, and other factors that are undefined—results in a change in and shortening of the normal hair-growth cycle [ 7 ]. This change is linked to the shortening of the anagen phase, an increase in the proportion of hairs in catagen, and the lengthening of telogen resulting Ahir hair loss, or alopecia uealth 78 ].
The hair cycle is regulated mainly by small specialized Foavonoids follicles. Hair follicles are located Flwvonoids the root of the Flavohoids within the skin [ 9 ].
One lFavonoids the most hwalth components of the Flavoniods follicle is a specialized population of mesenchymal cells called the dermal papilla DP [ 9 ]. The Bair provides important anf signals to heatlh hair follicle; therefore, it has a pivotal role in hair induction, growth, Flavonoidz cycling [ 8 ].
In alopecia Productivity and focus tips, the hair follicle becomes Flavvonoids, and this can lead to decreased induction of Multi-ingredient weight loss pills growth by the DP [ 10 ].
A number healrh studies focused on Gut health and sleep quality the mechanisms of hair Flavonnoids and ehalth therapeutic candidates have been Honduran coffee beans using mouse Flavonoidd with hair helth phenotypes as heqlth as human DP anx.
Mouse skin is different, however, from human skin with respect to Flavooids hair cycle, skin function, stem cell activity, and hormonal dependence hait 11 ]. It has also been reported that mice do not Promoting digestive balance from androgenetic alopecia, which is the Flvonoids common type of hair loss disease in humans [ Flavonoidw ].
Due to these limitations, it is aand to use human DP cells; Flavknoids, it is known that the common monolayer-based animal cell hajr 2D healthh does Flavoboids support the potential of DP cells to induce hair growth [ 13 Flavonoifs.
Recent research anr resulted in the development of the 3D culture system to enable formation of DP spheroids that have in vivo, Flavonoids and hair health, DP-like Flavonoies [ hwalth ]. Flavinoids culture Metabolism-boosting dietary supplement has been accepted znd hair induction studies because the Flavonoirs of hair growth is reproducible.
The 3D DP spheroids have also been shown to induce hair haiir de novo when transplanted [ healh15 Speed optimization methods. At the molecular level these results can be correlated Gut health and sleep quality yair expression of DP signature Restoring hydration to aging skin, including alkaline phosphatase ALPLversican VCANfibroblast growth factor 7 FGF7 healyh, and bone morphogenetic protein 2 BMP2.
DP cells are known to provide signals including FGF7 and BMP2 Flavonoida stimulate initiation of the anagen phase in hair follicles [ 16 ]. ALPL is a DP-specific marker that maintains the hair-inductive function [ 17 ].
VCANadditionally, is a component of the extracellular matrix that plays a role in hair follicle formation [ 17 ]. In this study, we have demonstrated the effect of silibinin on hair growth induction in 3D DP spheroids. Silibinin induces AKT-dependent gain of cell viability; this result was correlated with increase in the size of DP spheroids.
Additionally, we have observed that silibinin treatment significantly increases expression levels of DP signature genes. Therefore, our results indicate that silibinin may be a therapeutic candidate for hair loss treatment.
A selective phosphatidylinositol 3-kinase PI3K inhibitor, LY, and silibinin were purchased from Sigma-Aldrich USA. Three-dimensional 3D culture of DP cells was performed as previously described [ 19 ]. Briefly, cells were maintained in 2D culture as described above. After the formation of the unified spheres, the spheres were treated with silibinin for 48 h.
Finally, the diameters of the spheres were measured by phase-contrast microscopy. Briefly, 1 × 10 4 cells were seeded per well in well plates and maintained in complete medium for 24 h. After incubation, the cells were treated with the indicated doses of silibinin and incubated for a further 48 h.
WST-1 solution was subsequently added to each well and allowed to remain for 0. Cell viability was determined by measuring absorbance at nm using an iMark microplate reader Bio-Rad Laboratories, USA. pSV-β-gal plasmid was used as a control for transfection efficiency.
Twenty-four hours after transfection, the cells were grown by the 3D culture method and were subsequently treated with silibinin alone or in combination with LY Sigma, USA.
After 24 h of treatment, the cells were lysed using passive lysis buffer Promega and the lysates were incubated with D-luciferin Sigma-Aldrich to determine luciferase activity, which was then measured using a Glomax 96 Microplate Luminometer Turner BioSystems, USA.
β-gal activity was analyzed using the Luminescent β-galactosidase Detection Kit II Clontech Laboratories Inc.
Relative luciferase activity was determined by normalizing the levels to β-gal activity. Total cell lysates were prepared, and protein extracts were obtained after lysis for 30 min at 4°C in RIPA buffer 50 mM Tris- HCl, pH 7. The primary antibodies used for immunoblotting analysis were as follows: antibodies against NCAM ab and ALPL ab purchased from Abcam UK ; antibodies targeting AKT 5G3p-AKT Sand β-catenin from Cell Signaling Technology USA ; and the antibody against β-actin a from Sigma-Aldrich.
Following incubation with the primary antibodies, the membranes were incubated with goat anti-mouse or goat anti- rabbit horseradish peroxidase-conjugated secondary antibodies Cell Signaling Technology, USA.
The stained bands were visualized by using the Pierce ECL western blotting substrate Thermo Scientific, USA. β-actin was used as a loading control.
Total RNA was extracted from human DP spheres using TRIzol reagent Invitrogen; Thermo Fisher Scientific. cDNA was synthesized from 2 μg of total RNA using M-MLV reverse transcriptase Invitrogen. All analyses were performed with triplicate independent experiments. Before the evaluation of silibinin as an agent of hair induction in human DP cells, we sought to investigate its potential cytotoxicity and overall effect on viability in these cells Fig.
First, human DP cells were cultured in a monolayer followed by treatment with the various doses 0 to μ M of silibinin for 24 h. As shown in Fig.
The decrease in viability was significant compared to that observed with control DMSO-treated cells. Noteworthy was an increase of Next, we investigated the effect of silibinin on viability in 3D-spheroid-cultured, human DP cells.
To form DP spheres, cells were seeded and incubated to be grown in hydrogel-coated, low attachment round surfaces as described in Materials and Methods. Unlike the results with 2D-cultured DP cells, we found that treatment of 3D-spheroid-cultured, human DP cells with lower doses—less than 20 μ M—of silibinin significantly increased cell viability in a dose-dependent manner Fig.
A significant cytotoxic effect was observable only in cells treated with the highest dose of silibinin Fig. Overall, these results suggest that silibinin has a viability-promoting effect in 3D-spheroid-cultured, human DP cells. We have, considering the function of Akt, performed experiments to determine if the viability-increasing effect of silibinin might be mediated by Akt activation in 3D-spheroid-cultured, human DP cells.
Cells were incubated to be self-assembled for sphere formation and treated with 0 to 10 μ M silibinin for 24 h. Akt protein levels and phosphorylation status were analyzed using immunoblotting assays with specific antibodies.
As expected, silibinin was found to increase the level of Akt phosphorylation in a dose-dependent manner Fig. Next, we investigated the role of Akt phosphorylation in the viability-promoting effect of silibinin in human DP cells.
We confirmed that silibinin was able to increase the viability of 3D-spheroid-cultured, human DP cells in an Akt-specific manner; the increase in viability was not detectable in controls treated with LY, a specific inhibitor of the PI3K-mediated Akt activation Fig.
These results are indicative that silibinin promotes viability through Akt activation in 3D-spheroid-cultured, human DP cells. Recent reports have revealed that the ability of DP cells to form spheroids is connected to their potential to induce hair growth [ 15 ].
We therefore carried out experiments to investigate whether the influence of silibinin on the viability of 3D-spheroid-cultured, human DP cells can promote DP sphere formation. Human DP cells were grown in the 3D culture system followed by treatment with silibinin for 24 h.
The size of the DP spheroids was analyzed and quantified using a microscopy-based image acquisition and sphere diameter analysis. The silibinin treatment-induced increase in the size of DP spheres was notably significant compared to that seen in DMSO-treated DP cells Fig. These results suggest that silibinin enhances the formation of DP spheroids in vitro.
This effect was, however, nullified by LY treatment. qRT-PCR analysis of mRNA levels revealed increased expression of target genes in silibinin-treated 3D DP spheroids than in control spheroids.
We next examined whether silibinin can influence expression of DP signature genes that are important regulators of in vivo DP inductivity [ 18 ]. DP cells were grown in the 3D culture system followed by treatment with silibinin for 24 h.
Using a qRT-PCR assay, we determined the expression levels of DP signature genes, including ALPLVCANFGF7, and BMP2. To verify these data at the level of the protein, immunoblotting was performed using specific antibodies. We were able to demonstrate that the levels of these proteins were also increased by silibinin treatment of 3D DP spheroids Fig.
In this study, we have evaluated the potential effect of silibinin on hair growth induction in 3D-cultured DP cells. Therefore, it is important not only to understand the etiologic factors and molecular mechanisms behind hair loss, but also to develop natural candidates for the treatment of this condition.
Oxidative stress is an important factor that contributes to the aging of skin and related dermatological conditions. The knowledge that silibinin acts as a scavenger of reactive oxygen species ROS has led to its widespread dermatologic applications for the prevention of aging in skin [ 1 ].
The DP cells of lopecia patients have been shown to display elevated levels of ROS, and this has been proposed to contribute to the etiology of hair loss [ 22 ].
Despite these cues, there has been no study so far to evaluate the potential role of silibinin in the induction of hair growth. In this study, we have addressed this gap-in-knowledge using the 3D spheroid DP culture model. The turnover of hair follicles occurs over a course of a cycle that includes the growth and proliferation anageninvolution catagen and resting telogen phases; shortening of the anagen phase is a common sign observed in alopecia [ 23 ].
Therefore, studies for developing new therapies and identifying potential agents to inhibit hair loss have focused on the effect of hair follicle DP proliferation, as commonly measured by a cell viability assay [ 2324 ]. Studies have also indicated that AKT promotes dermal papilla cell survival.
Additionally, studies analyzing various anti-alopecia candidates have demonstrated the hair growth-promoting effects of AKT activation in DP cells [ 2325 ]. Our studies reveal that there is a dose-dependent increase in the cell viability and the p-AKT levels with the total AKT protein level remaining unchanged; this is indicative that silibinin induces AKT activation in 3D-cultured DP cells.
As mentioned above, 2D-cultured DP cells lose their ability to induce hair growth; however, three dimensional- culture conditions can make DP cells aggregate to form spheroids that are morphologically similar to intact papillae [ 13 ].

Introduction Although hair loss does not generally represent a serious health issue, it is a matter of interest as it may reduce confidence and lead to social anxiety, particularly in patients with alopecia, who manifest psychiatric symptoms, including depression, social phobia and anxiety, compared with normal individuals 1 , 2.
Materials and methods Preparation of PBE Pinus thunbergii growing next to the seashore of Gangneung Republic of Korea was gathered and its outer bark was harvested specimen no. Qualitative analysis of PBE Total phenol content The total phenol contents were determined by Folin-Ciocalteu's colorimetric method 22 using gallic acid as a standard for the calibration curve.
Total flavonoid content The total flavonoid contents were determined by the aluminum nitrate method 23 using quercetin as a standard for the calibration curve. Topical application of PBE and hair growth-promoting score HGPS In accordance with precedent studies by our group 3 , 25 , topical application with PBE was performed.
Tissue preparation for histological analysis The histological sections of the dorsal skin were prepared according to a previously described method Immunohistochemical staining To examine alterations in inflammatory cytokines and growth factors in the dorsal skin tissues between the groups, immunohistochemical staining was performed in accordance with certain previous studies with minor modifications 3 , Table I.
