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 alone has led to hair regrowth in the temples and hairline. The user is considering oral minoxidil or dutasteride but prioritizes health first.
Using Tretinoin every other day with daily Minoxidil may help with hair regrowth, and some users find it more effective than daily use. There are concerns about irritation and absorption, but small amounts seem to minimize harm.
