Review of the Literature

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

The user had a hair transplant with Estenove, rating the overall experience 6/10 due to logistical issues, unmet expectations, and dissatisfaction with the results. They advise against pricier packages and express regret over the asymmetrical hairline, despite good customer service and post-op care.

Finasteride and Dutasteride are under review in the EU due to concerns about side effects like depression, but they are unlikely to be banned. Access to these medications varies, with easier availability in the UK compared to some EU countries.

Dutasteride is more effective than finasteride for hair loss, especially at the crown and midscalp, but both have similar side-effect profiles with low incidence of sexual adverse events. Improvement is measured visually, and significant results may take over 12 months to appear.

Dutasteride at 0.5 mg/day does not significantly alter allopregnanolone levels, but higher doses (2.5 mg/day) do. Dutasteride may also have anti-neuroinflammatory effects, but the impact on neurosteroids is still debated.

The review discusses traditional hair loss treatments like minoxidil and finasteride, and newer options like Low-Level Laser Therapy, microneedling, and platelet-rich plasma for androgenetic alopecia. It highlights the need for more high-quality trials to assess these treatments' effectiveness and standardized protocols for emerging therapies.
