A number of factors can influence hair growth, so you may need to return for several visits. The total number of sessions required varies depending on the individual. Fifteen to 30 sessions are usually necessary for an optimal outcome, depending on the area of the body, the density of the hair, and your aesthetic goals. Treatments are usually spaced about a week or two apart and each treatment typically takes between 15 minutes to one hour. Following your treatment, you might experience a slight reddening of your skin, but this subsides within 15 minutes to 24 hours. Electrolysis is a safe and effective treatment that doesn’t involve any harsh chemicals or substances. If you’re considering electrolysis, you should take time to do your research and make sure it’s the right choice for you and that you have a qualified and trained professional.
