Studies on the Mode of Action of Vitamin A1

Topical Vitamin D3 may stimulate hair growth and has been used for Alopecia Areata. There is a question about the lack of research on its use for Androgenetic Alopecia (AGA).

Betacarotene's effect on hair loss is discussed, with concerns about excessive vitamin A. The user also questions if 15mg melatonin impacts vitamin A levels.

Hair loss theory suggests imbalance between Vitamin D Receptor (VDR) and Androgen Receptor (AR) activation. Proposed treatment includes upregulating VDR, downregulating AR, and improving mitochondrial health.

The conversation discusses using B6 and Zinc to inhibit 5ar activity, similar to Fin and Dut. Minoxidil is mentioned as a supplementary treatment.

Vitamin D deficiency can hinder hair recovery, and addressing it may help with hair loss. Hair loss may result from various issues like excess DHT, vitamin deficiency, or scalp inflammation.

Taking oral Vitamin D alongside topical minoxidil improves hair density more than using minoxidil alone. Users discuss Vitamin D dosages, potential benefits, and the importance of combining it with Vitamin K2.
