Laser hair Growth Therapy (LLLT) stimulates new hair growth and thickens existing hair. It is effective for treating thinning hair and Alopecia areata. There are FDA-cleared products, such as combs, caps, and helmets, that can increase hair thickness and density.
How It Works
Laser hair growth therapy uses low-intensity laser light to stimulate hair follicles and promote new hair growth. It is effective for pattern baldness, thinning hair, and alopecia. It can also enhance the results of hair transplants or PRP treatments. During the treatment, a cap, comb, or helmet-type LT machine is placed over your head while you sit in front of a screen and relax. The skin may become hot, but most people tolerate it well. Numbing cream can be used to reduce discomfort. The laser light penetrates the skin and stimulates the cells in the hair follicles to produce more energy, which promotes hair growth. This process, called photobiomodulation, is similar to how plants use sunlight for photosynthesis.
Safety
Laser hair growth devices use low-power laser light, which passes through the skin and absorbs pigment in hair follicles, destroying them and stopping future hair growth. Cooling devices or gels may protect the skin and reduce discomfort during treatment. A doctor will press the laser device against your head or the area with unwanted hair. Goggles protect your eyes; unwanted hair may be shaved off before treatment. The number of treatment sessions required depends on your hair and skin color. Temporary hair shedding may occur after treatment, but it usually resolves independently. It is essential to avoid sun exposure before and after treatment and to use sunscreen with at least SPF30.
Side Effects
Laser hair growth treatments should not be done during pregnancy or breastfeeding. They may also be unsafe for people with certain medical conditions or taking certain medications. Burns or changes in skin color can occur if an inexperienced laser specialist uses inappropriate technology, so it is essential to have a board-certified dermatologist involved.
Cost
Laser hair removal may cost more than shaving or waxing, but it can save time and effort and reduce razor bumps and ingrown hairs. It is also safer for the skin compared to plucking or shaving. The cost depends on the area being treated and the type of laser used. Diode lasers work on all skin types faster, while Alexandrite and Nd: YAG lasers may not be as effective on light or fine hairs. Choosing a trustworthy provider specializing in dermatology or cosmetic surgery for laser hair removal is essential. Health insurance usually does not cover this procedure, but flexible spending accounts may be used.
