How To Use Derma Roller and Minoxidil to Regrow Hair!
Anti hair loss therapy with the derma roller is used to induce collagen formation, neovascularization and growth factor production of treated areas.
Micro-needling is a technique that promotes controlled tissue injury through the formation of micro-channels.
Scientific evidence suggests that micro-channels created by derma roller promote the absorption of anti-hair loss products applied topically e.g. Minoxidil (Rogaine), topical Fiansteride, etc.
Micro-needling with a derma roller 1.5 mm can improve hair count on a treated area without adding any topical products! Study
Derma Rolling Frequency
Frequency of using a derma roller for hair regrowth depends on the size of its micro needles!
The longer the micro needles are, the lower the frequency. The shorter the micro needles, the more often you can use it!
How to Derma Roll
- Choose a derma roller of your choice (preferably 1.5 mm)
- Start rolling it on your scalp in a longitudinal, vertical, and diagonal directions until you experience pinpoint bleeding (erythema)
- Your derma rolling session is finished. Wait 24 hours before you apply Minoxidil (Rogaine), topical Finasteride or any other alcohol- or propylene glycol-containing topical product which might irritate your scalp.
When you can start seesing results?
First hair regrowth can appear after 12 weeks of doing derma rolling. In this study (below) they compared Minoxidil 5% + Micro-needling with the derma roller 1.5 mm vs Minoxidil 5% only and after 12 weeks the hair regrowth in the derma roller + Minoxidil 5% group was already significant (better than in the Minoxidil 5% group).
How many hairs can you regrow?
This will depend on 2 factors.
How many hairs have you already lost? If you have already clear bald spots on your scalp (or spots with vellus hair – 2 mm long hair), derma roller won´t help you regrow any new hair in these areas. Derma roller only works on the areas with terminal hair incl. terminal hair which started to miniaturize recently.
How well do you respond to conventional treatments like Minoxidil 5%? Since derma roller potentially acts as a transcutaneous penetration enhancer, it will greatly benefit all patients who are positive responders to Minoxidil. We know that combining Minoxidil + Derma roller can regrow more hair than using Minoxidil or Derma roller separately.
Derma Rolling for non-responders to Minoxidil and Finasteride
This study observed (unfortunately only) 4 patients who failed to respond to conventional therapy for treating male pattern hair loss – Minoxidil 5% and Fiansteride 1 mg.
Case 1 - 6 months after Derma Rolling
Case 1 — A 30-year-old male was suffering from AGA since 8 years. He was on oral finasteride and topical 5% minoxidil regularly since 4 years and also had underwent hair transplantation surgery 2 years ago. He reported an arrest in hair loss but was unsatisfied in terms of cosmetic scalp coverage.
Case 4 - 6 months after Derma Rolling
A 40-year-old male with female pattern type III of hair loss was taking conventional therapy for over 3 years but unsatisfied with respect to new hair growth
