| I | Very light skin; always burns and does not tan. | Hair may be blond, red, light brown, or dark brown. | Shaving, trimming, depilatory creams after a patch test, waxing, threading, and electrolysis. Light-based treatment may work best when the hair is substantially darker than the skin. | Contrast between light skin and dark hair can support laser-based treatment. Blond, red, gray, or white hair contains less melanin and usually responds poorly to laser or intense pulsed light; electrolysis may be considered for individual hairs. |
| II | Light skin; usually burns and tans minimally. | Hair may be blond, light brown, brown, or dark brown. | Shaving, trimming, depilatory creams after testing, waxing, threading, electrolysis, and professionally supervised laser treatment when hair is darker than the skin. | Avoid treatment over recently tanned skin. A qualified professional should select settings according to skin tone, hair color, hair thickness, and body area. |
| III | Light to medium skin; may burn and gradually tans. | Hair is commonly medium brown or dark brown, but may be lighter. | All temporary methods may be options. Laser treatment can be effective for dark hair when performed with an appropriate device and settings; electrolysis works independently of hair pigment. | Moderate pigment in the skin increases the need for careful assessment and conservative settings. Test spots and sun protection may reduce the risk of pigment changes. |
| IV | Medium or olive skin; may burn mildly and tans easily. | Hair is often dark brown or black. | Shaving, trimming, depilatory creams after a patch test, waxing, threading, electrolysis, and carefully selected professional laser treatment for dark hair. | The surrounding skin contains more melanin, so laser treatment requires an experienced practitioner, suitable technology, cooling, and conservative energy selection. Temporary lightening or darkening of the skin can occur. |
| V | Brown skin; rarely burns and tans readily. | Hair is usually dark brown or black. | Shaving, trimming, threading, and electrolysis are pigment-independent options. Professional laser treatment may be possible with equipment and settings selected for darker skin. | The risk of burns and post-inflammatory hyperpigmentation is higher if treatment is poorly matched. Seek an experienced, qualified provider and discuss a test spot before a larger area. |
| VI | Deeply pigmented brown to black skin; never burns and tans deeply. | Hair is commonly dark brown or black. | Shaving, trimming, threading, and electrolysis. Laser treatment should only be considered after assessment by a qualified professional using technology and settings appropriate for deeply pigmented skin. | Laser energy can be absorbed by melanin in the skin as well as the hair. Carefully controlled treatment, cooling, sun avoidance, and monitoring are important to limit burns and pigmentary changes. |
