baicalin, active ingredient against AGA

[Shinobi]

The inhibitory effect of Scutellaria baicalensis extract and its active compound, baicalin, on the translocation of the androgen receptor with implications for preventing androgenetic alopecia.

Androgens affect several human skin and prostate functions, and the androgen receptor is crucial for regulating the androgen-related mechanisms. In this study, we assessed the antagonizing effects of a Scutellaria baicalensis extract and its main component baicalin on proliferation of human scalp dermal papilla cells. First, the extract and baicalin slightly dissociated the radioisotope-labeled androgen receptor-agonist complex in the androgen receptor binding assay, and the IC50 values were measured to assess the androgen receptor antagonistic effect of the extract (93 µg/mL) and baicalin (54.1 µM). Second, the extract and baicalin treatments dose-dependently inhibited the overgrowth of LNCaP prostate cancer cells, which were stimulated by dihydrotestosterone. Third, the extract and baicalin inhibited nuclear translocation of the androgen receptor stimulated by dihydrotestosterone in human dermal papilla cells. Additionally, the extract and baicalin enhanced proliferation of human dermal papilla cells in vitro. These results show that the extract and baicalin inhibited androgen activation signaling and promoted hDPC proliferation, suggesting that they could be used as active ingredients for treating androgen-associated disorders, such as androgenetic alopecia.

Baicalein Protects Cardiomyocytes Against Mitochondrial Oxidant Injury Associated with JNK Inhibition and Mitochondrial Akt Activation.

Baicalein, a flavonoid derived from Scutellaria baicalensis Georgi, possesses cardioprotection against oxidant injury by scavenging reactive oxygen species (ROS). Few studies investigate whether baicalein protection is mediated by attenuating mitochondrial ROS and modulating the prosurvival and proapoptotic signaling. Primary cultured chick cardiomyocytes were used to study the role of baicalein in mitochondrial superoxide [Formula: see text] generation and signaling of Akt and JNK. Cells were exposed to H 2 O 2 for 2 h and baicalein was given 2 h prior to and during 2 h of H 2 O 2 exposure. Cell viability was assessed by propidium iodide and DNA fragmentation. H 2 O 2 (500 μM) significantly induced 45.3 ± 6.2% of cell death compared to the control (p < 0.001) and resulted in DNA laddering. Baicalein (10, 25 or 50 μM) dose-dependently reduced the cell death to 38.7 ± 5.6% (p = 0.226); 31.2 ± 3.9% (p < 0.01); 30.3 ± 5.3% (p < 0.01), respectively. It also attenuated DNA laddering. Further, baicalein decreased intracellular ROS and mitochondrial [Formula: see text] generation that was confirmed by superoxide dismutase PEG-SOD and mitochondria electron transport chain complex III inhibitor stigmatellin. In addition, baicalein increased Akt phosphorylation and decreased JNK phosphorylation in H 2 O 2-exposed cells. Moreover, baicalein augmented mitochondrial phosphorylation of Akt Thr308 and GSK3β Ser9, and prevented mitochondrial cytochrome c release assessed by cellular fractionation. Our results suggest that baicalein cardioprotection may involve an attenuation of mitochondrial [Formula: see text] and an increase in mitochondrial phosphorylation of Akt and GSK3β while decreasing JNK activation.

Baicalin scavenges reactive oxygen species and protects human keratinocytes against UVC-induced cytotoxicity.
Wang SC, Chen SF, Lee YM, Chuang CL, Bau DT, Lin SS.

Long-term exposure to solar ultraviolet (UV) radiation can cause multiple skin disorders, including skin cancer. Protection against UV-induced damage is, therefore, a worldwide concern. Baicalin, a major component of traditional Chinese medicine Scutellaria baicalensis, has been reported to have antioxidant and cytostatic effects on normal epithelial and normal peripheral blood and myeloid cells. In the current study, we examined whether baicalin could also effectively protect human keratinocytes from damaging short-wave UVC irradiation. Baicalin-scavenged reactive oxygen species increased within 2 h after UVC radiation. Baicalin also abrogated UVC-induced apoptosis. In addition, we identified the major products after UVC radiation with T4 UV endonuclease, finding that baicalin prevented cyclobutane pyrimidine dimer formation induced by UVC. Furthermore, baicalin also prevented formation of oxidative adducts induced by UVC. Our results demonstrated the utility of baicalin in assessing the potential contribution of traditional Chinese medicinal agents in therapy of UVC-induced genomic damage to skin and suggest potential application of these agents as pharmaceuticals in prevention of solar-induced skin damage.


A brand tested an active ingredient composed of mainly baicalin on hair loss and the result seems actually very good, especially for a 3 months treatment:

just look in google for the pdf baicapil

human vivo result are (unlike some other cosmetic brand, they also used a placebo group, wich is very smart):


1/ increase of 68.6% in the A/Telogen ratio


2/ decrease of 60.6% on hairloss

3/ increase of 60% in hair density


it seems the company also patented the application use for baicalin for hairloss

Problem is their active ingredient called "baicapil" also contain some things we are not sure its positive such as soy and wheat sprout. If you remember, in another topic I explained some isoflavones could not be as good for hair, but long topic..

Im looking for the active ingredient baicalin only and we can dose it as they did for their formula (they advice between 2 and 4%) Problem is we dont know how much % of the baicalin they used since they speak more about the whole plant extract. We should for now use a pure baicalin not above the 2% range, but yeah until we have more details its still pure speculation.
