retinoic acid epidermal transdifferentiation embryonic skin epithelial-mesenchymal interactions Gbx1 Tgm2 TGF-β2 hair follicle formation Wnt/β-catenin pathway transcription factors skin morphogenesis skin differentiation therapeutic applications hair loss RA skin transformation skin development skin therapy

TLDR Retinoic acid helps change skin cells and is important for skin development and hair growth.

The document reviewed the role of retinoic acid (RA) in inducing epidermal transdifferentiation in embryonic skin, highlighting its ability to transform epidermal cells into mucosal epithelium through epithelial-mesenchymal interactions. Key molecular players included Gbx1, Tgm2, and TGF-β2. RA influenced hair follicle formation and barrier formation by affecting the Wnt/β-catenin pathway and various transcription factors. The study underscored RA's importance in skin morphogenesis and differentiation, providing insights into its broader regulatory roles and potential therapeutic applications for skin diseases and hair loss.

community Minoxidil Response Bottlenecks: Why Sulfation and Transport Matter (And Where Tretinoin Fits In)

in Research 461 upvotes 5 months ago

Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

community Tazarotene shows strong standalone hair regrowth potential, not just a Minoxidil enhancer. Backed by VEGF, HF regeneration, and angiogenesis pathways. Here’s why.

in Research/Science 132 upvotes 4 months ago

Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.

community Oral minoxidil vs Topical Minoxidil w/ Retinoic acid

in Minoxidil 6 upvotes 4 months ago

Topical minoxidil with retinoic acid is effective but causes scalp irritation, leading the user to consider switching to 2.5mg oral minoxidil. Oral minoxidil may cause body hair growth and heart-related side effects, so it's advised to use it under medical guidance.

community Minoxidil works only with Retinoic acid

in Minoxidil 316 upvotes 4 months ago

Minoxidil is more effective when combined with retinoic acid, such as tretinoin or tazarotene, enhancing hair growth. Some users experience significant regrowth, while others see minimal effects or side effects.

community Tretinoin aka retinoic acid, the minoxidil enhancer

in Product 8 upvotes 1 year ago

Tretinoin can make minoxidil more effective for hair loss treatment, but some users did not see improved hair density with this combination and had better results with dutasteride.
