What laser hair removal involves
Laser hair removal uses a device that sends pulses of light into the skin, aimed at hair follicles. It is usually done as a series of sessions spaced weeks apart, because hair grows in cycles. The number of sessions varies from person to person and area to area.
Skin tone and hair color both affect which device and settings fit. Common device types include diode, alexandrite and Nd:YAG lasers, and some providers use intense pulsed light. A licensed provider looks at your skin, hair and health history and decides what is suitable.
What a provider looks at first
Before laser hair removal, a licensed provider usually checks:
- your skin tone, often using a skin type scale
- your hair color and thickness in the area
- recent sun exposure, tanning or self-tanner
- medicines that raise light sensitivity, including some antibiotics and acne medicine by mouth
- pregnancy or breastfeeding
- a history of cold sores, if the face is involved
- tattoos or moles in the area
- hormone-related conditions that affect hair growth
These answers guide device choice, settings and timing.
Write down your hair removal history
Your past hair removal tells a provider a lot. Before a consultation, write down how you have removed hair in each area: shaving, waxing, threading, plucking, creams, or earlier laser or light treatments. Note roughly when you last did each one.
Add anything you noticed, such as ingrown hairs, irritation or dark marks afterward. Then list medicines, supplements, recent sun and pregnancy or breastfeeding.
Bring this with your questions. A licensed provider looks at your skin and hair, considers your notes, and decides what is suitable.
Questions about laser hair removal
How many laser hair removal sessions will I need?
It varies. Laser hair removal is usually a series of sessions spaced weeks apart, and the number depends on the area, your hair, your skin and the device. A licensed provider can say what is typical after seeing you, and nobody can promise a set number.
Is laser hair removal an option for blond, gray or red hair?
Very light hair can be hard for many lasers to target, because most devices rely on pigment in the hair. Some providers may still discuss options. Ask plainly at the consultation, and a licensed provider will tell you whether it is suitable.
Should I shave before a session?
Many providers ask you to shave the area shortly before each session and to avoid waxing, plucking or hair removal creams for a while beforehand. Instructions differ, so follow the ones your provider gives you.
