Both laser and electrolysis are effective tools to achieve permanent hair removal. Both are a process of treatments. How many treatments for both varies for each individual depending on their needs. Hairs have three growth cycles; anagen, catagen, telogen which means growing, resting, shedding, so not all hairs are present during treatment. Hairs are usually not at the same growth cycle during the treatments, which is why several appointments are necessary.
Unwanted hair often develops during puberty, pregnancy, or menopause and may also be a side effect of polycystic ovaries, thyroid malfunction or other hormonal imbalances. Hair usually gets longer to get rid of in theses hormonal conditions because the body will usually continuously stimulate new hairs. I can only destroy hairs that are present, I cannot destroy future hairs. Often after all the hairs are removed, patients may need what I call maintenance treatments of about 10 minutes once a month, until their body stops producing new hairs.
Genetics are another very important factor that affect hair growth. Mediterraneans are the hairiest while Native or Asian are the least. Even though each person is different and tolerates pain differently (some don't feel a thing while others need numbing crème), all patients require a hair, skin, and medical evaluation during consultation.
