Microneedling's effectiveness for hair regrowth is debated, with mixed results from studies. Some believe it helps with blood flow and scalp health, while others see it as largely ineffective.
A 22-year-old using finasteride and 2% ketoconazole shampoo for hair loss sees mixed results after three months, with some improvement at the crown but worsening at the temples. Suggestions include waiting 6-12 months, considering dutasteride, adding minoxidil, microneedling, caffeine tonic, and retinol.
Some individuals do not respond to oral minoxidil for hair loss, despite it generally working by improving blood flow to hair follicles. Factors like metabolism, drug interactions, and individual variations in the drug's activation may influence its effectiveness.
Tretinoin may enhance the effectiveness of minoxidil for hair regrowth by increasing enzyme activity and skin permeability, but its standalone impact is limited. Some users experienced improved hair growth with tretinoin, while others found it worsened their condition.
The conversation discusses the difficulty of applying tretinoin 0.025% cream on the scalp and considers switching to a gel for easier application. It also mentions that a liquid solution, ideally combined with minoxidil, may be more effective for hair treatment.
