Laser hair removal, in plain terms
A few basics cover most of what people want to know first:
- A handheld device sends light pulses into the skin over the area.
- The light is aimed at the pigment in hair.
- Sessions are usually spaced several weeks apart.
- Most people have a series of sessions. How many varies.
- Skin tone and hair color affect which device fits.
- Shaving the area beforehand is usually requested. Waxing and plucking usually are not.
A licensed provider decides what is suitable at a consultation, after asking about your skin, hair and health.
Medicines and health history
Some medicines make skin more sensitive to light, which matters for laser hair removal. Examples include some antibiotics, acne medicine taken by mouth, and some herbal supplements such as St John's wort. A provider will also want to know about hormone-related conditions that affect hair growth, a history of keloid scars, cold sores, and pregnancy or breastfeeding.
Bring a full list of medicines and supplements to the consultation. Do not stop any prescribed medicine without talking to the person who prescribed it. The licensed provider weighs it all and decides what is suitable, or whether to wait.
Planning sessions around your calendar
Laser hair removal is usually a series of sessions spaced weeks apart, and the number varies. Before the consultation, look ahead at your calendar. Note beach trips, sunny vacations and events where you would rather not have a fresh session.
Many providers ask you to keep sun exposure low during a series, so the time of year can matter. Bring your dates, and ask the provider how they would space sessions around them. They can then decide what is suitable and when to start.
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.
Does skin tone affect laser hair removal?
Yes. Skin tone and hair color affect which device and settings fit. Some devices are generally used for lighter skin, and others, such as Nd:YAG lasers, are often chosen for deeper skin tones. Ask the provider which device they use and why it suits you.
Who may operate a hair removal laser?
That is set by each state, including California, and rules differ. Some states limit it to physicians and nurses, while others allow trained technicians under supervision. Ask who will run your sessions, what training they have and who supervises them.
