There’s no way they can treat brown hair.
A good close shave should be given to the area to be treated, or the energy will not reach the roots.
You should not be shaving yourself prior to your first appointment.
They will pretend IPL can treat your fine hairs, sorry but that’s a myth.
Not everyone is suitable for IPL hair removal due to skin tone and hair colour. If you don’t have black hair, you have no chance of seeing results.
