How laser hair removal works
Tria's 4X laser targeting a hair follicle The technology behind how laser hair removal devices work is pretty straightforward. The laser beam from a hair removal device targets the pigment in the hair follicle on freshly shaven skin. The only way that the laser can find the pigment is if the skin tone is lighter than the pigment color of the hair. If the skin is darker than the hair's pigment, or if the hair color has little to no pigment in it, the laser cannot find the hair follicle--resulting in the laser not treating those hairs. This type of diode laser technology means that certain skin tones and hair colors will not be affected by the treatment. White or grey hair, blonde and red hair do not have enough pigmentation for the laser to target. Since I have different colors of body hair, I can treat my legs and wherever the hair is light brown to black, but the hair that is red or blonde, I cannot treat. If your hair is light brown to black, and your skin tone is pale to light tan, you are a great candidate for at-home laser hair removal.
Hair Growth Phases
Your hair color and skin tone are not the only factors that come into play with laser hair removal. Each hair on your body is in a different hair growth phase, and this is very important for successful laser hair removal. Let's take a look at each phase and what it means for laser.
- Anagen Phase
- Catagen Phase
- Telogen Phase
- Exogen Phase
Will Tria Lasers Work for You?
The first step in deciding if Tria's hair removal lasers will work for you is to take a look at the skin tone and hair color chart. The chart will guide you to make sure that your skin tone and hair color combination will work with diode laser technology. As you can see here, the laser will work on pale to light brown skin tones, and only on black to light brown hair color. What could happen if your skin tone is darker than light brown and you used the laser? The answer is that the laser could target the skin instead of the hair and cause pain and damage. The great thing about the Tria at-home hair removal laser is that there is a safety feature on the device that only allows the laser to unlock when the skin tone is within a safe range. You will still need to use precautions when using the laser over dark moles. You can purchase white circle stickers to place over the moles to make sure they will not get hit with the laser during treatments. Definitely avoid any tattoos!
What Type of Hair Removal Methods Work for Dark Skin?The good news is that there are options for hair removal for those with dark skin tones. These options are available only in clinics and cannot be performed at home, so you will have to make an appointment and most likely go through a consultation first.
Nd:YAG LaserThe Nd:YAG laser (also known as YAG) works by targeting the blood supply that is attached to the hair follicle. This laser works safely over darker skin tones as it does not target the melanin in the skin. Be prepared to go in for many sessions with this laser since the average sessions will be about 8 to 12 to achieve permanent results. As always, I remind you to do your research on the clinic you book--check reviews first! Depending on the area being treated, the average cost of these treatments are about $300 per session.
ElectrolysisThis method of hair removal will work on all skin tones and hair colors -- this will work on blondes with light body hair and redheads! Electrolysis is highly effective technology, but there are some drawbacks that I'd like to mention when choosing this option. Unlike laser, this method works by manually placing a wire into the hair follicle underneath the skin. An electric current moves down the wire to destroy the hair follicle. The person performing the procedure must be a licensed or certified electrologist that has a valid license to work within your state. It can take 8 to 18 months to see full permanent results with about 2-4 treatments spaced 6 weeks apart. A common side effect in those with darker skin tones is Post Inflammatory Hyperpigmentation that can take up to a year to fade. I also want to mention that electrolysis can be painful, even with numbing creams applied. As with any hair removal method, regrowth is common and touch-ups are necessary. I wish you the best of luck on your hair removal journey! If you have any questions for Tria Beauty, please reach out at firstname.lastname@example.org
