Hello and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Laser
hair removal works by destroying the hair follicles so they do not produce hair anymore.
Biotin, on the other hand, although not clinically proven, is thought to contribute on the quality of hair. So, in this aspect, there would be no clash between the two.
However, biotin is known to cause breakout in the skin causing an
acne flare, which is not something you'd want when receiving
laser therapy. For this reason, I recommend you postpone biotin use until after your
laser treatment is completed. Wishing you all the best.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Ornela Ademovi
