The hair in contact with the follicle is only in the growth phase so the removal is only possible in this phase. The procedure thus needs to be renewed. The epilation procedure has the most effect on light skin and dark hair.
Typical reactions on the skin after epilation are: redness, which may last for several days, hives (redness of the skin with swelling), pruritus, very small scabs can appear in highly pigmented people. After laser epilation it is not recommended to expose your skin to ultraviolet rays (sun, solarium) for at least one month.
