How do I use Scalp activator/ derma roller?

Clean the Scalp Activator using alcohol disinfectant spray
Apply the roller device into scalp and roll evenly on the scalp
Work in small sections working the roller in a cross-hatch fashion until you have completely worked through the whole scalp.
For best result use in conjunction with Dense topical treatments 2-3 times a week and replace on a monthly basis to avoid the needle points getting blunt.
