Can pico laser remove hair?

Pico systems produce extremely brief pulses and are commonly discussed for pigment or tattoo concerns. Hair-removal lasers use a different treatment strategy: energy is absorbed by hair pigment and delivered toward the follicle. Results depend on the contrast between hair and skin, the body area, hair thickness and any hormonal influence on growth.

Unwanted hair can occur with hirsutism, while shaving may contribute to razor bumps and ingrown hairs. Recurrent painful lumps, drainage or scarring need assessment because they can occur with hidradenitis suppurativa rather than simple hair growth. Small rough bumps around follicles may instead fit keratosis pilaris.

Ask the provider to name the exact device and explain why it fits your hair and skin. Relevant options may include [Alexandrite Laser](/technology/alexandrite-laser/), [Diode Laser](/technology/diode-laser/) or [Nd:YAG Laser](/technology/nd-yag-laser/). Avoid plucking or waxing before a follicle-targeting session if instructed, and disclose tanning, medicines, active irritation, scars and a history of pigment changes.

A consultation should also cover shaving instructions, cooling, expected temporary redness and how the plan will be adjusted for sensitive or deeper skin tones. Treating an inflamed or infected area may need to wait.

Contact the clinic for blistering, severe pain, spreading redness, pus or colour change that is worsening rather than settling. Seek medical assessment for painful recurring nodules, tunnels, drainage or scars in skin folds, or for sudden excess hair with other hormonal changes. Persistent ingrown hairs may need treatment for both the hair and the inflammation.

Ask: Is this a hair-removal laser or a pico device? Which wavelength suits me? Should I shave, stop plucking or pause a product? How will you protect my skin from burns or pigment change? Could my hair growth signal hirsutism or another condition?
