community 3 days after a hair transplant
A user humorously shared their appearance three days after a hair transplant, sparking jokes and memes about their head shape. They remained positive, acknowledging the swelling and hoping for improvement.
community Where did this idea come from: dermastamp better than dermaroller?
Dermastamps are preferred over dermarollers for microneedling due to precision and reduced risk of scarring. Dermastamps allow for controlled, vertical needle entry, while dermarollers may cause more damage with sideways needle entry.
community Loosing hope after not seeing improvement in hair regrowth.
A 22-year-old male is not seeing hair regrowth after using minoxidil and finasteride for a year and additional treatments for three months. Suggestions include improving scalp absorption with sea salt and trying a lipid-based solution, microneedling, and possibly switching to dutasteride if no improvement after 1-2 years.
