    TLDR The study suggests that analyzing DNA can help treat hair loss, but more research is needed.
    The study examined the distribution of specific genes in 287 Romanian and 882 Brazilian patients with non-cicatricial alopecia, specifically androgenetic alopecia (AGA) and alopecia areata (AA). It found significant differences in the distribution of the GR-alpha, GPR44-2, SULT1A1, and CRABP2 genes between the two populations. The SULT1A1 gene, which predicts response to minoxidil treatment, suggested that minoxidil is recommended in half of the AGA and AA cases. Patients with AGA and high expression of SRD5A1 or PTGFR-2 may benefit from Dutasteride or Latanoprost treatment, respectively. The study also identified five specific SNPs with potential relevance in the genetic basis of alopecia. The study concluded that DNA analysis of patients with alopecia may contribute to successful treatment, but further extensive studies are necessary to confirm these findings.

      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.

      Lichen Planopilaris (LPP), a form of permanent hair loss, which can be mistaken for seborrheic dermatitis and is characterized by scalp itching, burning, redness, and dandruff. Treatment options discussed include steroidal creams, finasteride, minoxidil, and RU58841.

      In this conversation, 4990 discussed various treatments for hair loss, including oral minoxidil, PRP, transplan, Jak inhibitors, Dutasteride, Finasteride, Olumiant, Ketoconazole, RU58841, microneedling, baricitinib, and CCCA. They recommended scalp biopsies in unclear cases of DUPA, twice weekly to twice daily shampooing for topical minoxidil users, and two sessions spaced one month apart with follow up at month three to determine the effectiveness of PRP treatment.

      Microneedling for hair restoration involves daily use of a 0.3 mm device and weekly use of a 0.5 mm device. Combining microneedling with Minoxidil can enhance hair growth.
