Laser Hair Growth Vs Laser Hair Removal: Understanding the Difference

Lasers are one of the greatest innovations in the medical science. They are so dynamic and versatile to use for corrective eye procedures, accurate incision, and skin rejuvenation. Lasers are also used for competing functions- some wavelengths for hair growth and others to remove it. It may sound strange, but laser removal therapy and laser hair growth procedure both use laser light for treatment. So, what are the ways they use to achieve a different result or almost an opposite result?

Let’s identify the difference between them!

Laser Hair Removable

The technical term used for laser hair removable is selective photothermal lysis, in short SPTL. The process involves using of mild radiation via high-heat lasers. The purpose is to damage hair follicles enough to significantly lower down the growth of hair. It ceases growth of follicles for a long time.

The SPTL technique uses pulses of light generated by diodes and the wavelength is typically in the range of 694 nm to 1,000 nm. According to experts, the treatment works great on people who have both fair skin and dark hair because the procedure targets the pigment, melanin which plays a significant role in giving color to human hair. Although new hairs may still grow, they are finer and lighter in color than before.

The treatment is available in many salons. Consider undergoing the therapy under experts because it has some side effects like blisters, inflammation, irritation, swelling, redness etc.

Laser Hair Growth

The therapy uses “cold” or non-ablative lasers, known as low-level light therapy. It is best known as LLLT. The laser hair therapy is based on photochemistry (chemical effects of light) to stimulate hair cells in the follicle. It helps in increasing blood flow in the scalp and stimulates metabolism in catagen follicles, resulting in the production of anagen hair.

The low-level laser is radiated on the balding areas. Light of different wavelengths is absorbed by the outer dermis which accelerates chemical reactions within the cells. The photobiomodulation divides the follicle, thus resulting in long and strong hair growth. Unlike SPTL for hair removable, LLLT for hair growth has no adverse side effects. It is safe to use.

The treatment for low-level laser hair therapy lasts 6-12 months with around 45 minutes a session which is twice in a week at least. It also involves evaluation to monitor the progress.

Once the growth rate is improved, the clinic recommends a hair growth device to rip the maximum benefits of LLLT. People who find hard to take out some time from their busy schedules to visit the clinic periodically can use the device. It is safe to use because LLLT has no side effect.

On the contrary, the hair removable technique can’t be practiced at home because the result is not so effective. Only a skilled and trained laser removal technician adds efficacy to the procedure.
