There are certain tips that you can incorporate in order to facilitate this. These include the following:-
You can apply an exfoliating scrub at least thrice a week on the surface that has undergone a laser hair removal process. Exfoliating will allow the shedding process to proceed unhindered.
Cutting or shaving the re-growing hair:
You can cut or shave, but do not wax or tweeze. You need these hair follicles for the laser to work on them during your next appointment after the first laser hair removal treatment.
Use the sunscreen:
Continue using the sunscreen after the first laser hair treatment procedure. This is mainly to avoid tanning and create the right skin-hair contrast that will allow the laser tom to work on it.
