When to stop shaving and exfoliating before laser hair removal session?

It is best to shave the day before or day of treatment. This prevents the hair from absorbing the laser energy and causing burns. Do not tweeze or wax three weeks before or during laser hair removal treatment. Doing so removes the hair follicle the laser targets. Always remember to get your treatment done by an expert.

Shaving does not affect the hair in the follicle (beneath the surface of the skin) and so does not affect laser treatment.  In fact, as mentioned in another answer, shaving the day of the procedure is recommended to prevent strands of hair from absorbing the laser energy and decreasing the efficiency of the treatment or potentially causing burns.  Do not pluck hair or wax in an area to be treated for at least 2 weeks as these remove the hair follicle and leave no target for the laser.

You should shave the day of treatment. That way, the heat from the laser will penetrate deeper and not be lost in the long hairs. When the skin is healed and not red or tender, it's ok to start back on products.

Thanks for your question and we always recommend that you consult with a board certified dermatologist or plastic surgeon to learn all that you can about laser hair removal before you have it done.  For your question, it is best not to shave 2-5 days before the procedure as we need to have some hair present to allow the light to penetrate into the hair shaft.  Some providers will do the shaving before the procedure and that works as well.  And post-treatment, if there is a little redness and swelling, which is normal, wait to apply anything until that has disappeared.

Do not shave for two days prior to laser hair removal. The hair needs to be clipped prior to the laser treatment.
