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.
The user had a hair transplant and is asking when they can resume microneedling their forehead, which they did previously once a week with positive results on their crown. They are currently on a treatment regimen that includes oral finasteride, oral and topical minoxidil, ketoconazole shampoo, and black castor oil for moisturizing.
OP saw positive results from 4 months of finasteride, vitamin D3, and microneedling. They plan to add rosemary and castor oil but decided against using minoxidil.
Microneedling with 0.6 mm needles combined with 5% minoxidil is more effective for hair count and thickness than minoxidil alone or with 1.2 mm needles. Biweekly microneedling at 0.6 mm depth is recommended for better results in treating androgenetic alopecia.
