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 and microneedling both enhance hair growth through different mechanisms, with microneedling being considered safe for long-term use. Optimal microneedling needle length varies, but 0.8 mm is suggested for hair growth, and a Dermastamp is recommended to avoid skin damage.
