Minoxidil's effectiveness varies due to genetic differences in the SULT1A1 enzyme, affecting how well it converts to its active form, minoxidil sulfate. Hyper-responders may experience rapid hair growth and increased side effects, such as pericardial effusion, even at low doses.
A user discusses a company, Roots by Genetic Arts, that offers a genetic test for hair loss to create personalized treatments, and is curious about its legitimacy and the science behind it. The company tests 16 genes related to hair loss and compounds a topical treatment based on the results.
Minoxidil alone is not effective for significant hair regrowth; combining it with finasteride or dutasteride is necessary. Additional treatments like hair transplants, microneedling, or oral medications are recommended for better results.
Some people may not respond to topical minoxidil due to low SULT1A1 enzyme activity, but oral minoxidil can be effective. Tretinoin may enhance minoxidil's effectiveness, and some users prefer oral minoxidil despite side effects.
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.
