​Laser hair removal treatments are often pitched and advertised as a permanent solution to get rid of hair.

 

For most people who choose laser hair removal over other conventional hair removal method, permanent hair removal is not always the case.

Though some people are lucky to get away with the entire laser treatment session and never grow hair in the treated area again, it is very common for hair to regrow.

  

​The hairs mainly grow back due to their regular growth cycle. If you read our previous article “ What is IPL Hair Removal” then you know how IPL Hair Removal Devices and Lasers remove hair.

Hair in an active growth phase treated by the laser will be affected, the light emitted forces the root of the hair to separate from the cell wall and thus putting it in a dormant state.

Not every hair has the same growth cycle (meaning not all the hair will be damaged during laser treatment process) which is why some hair will continue to grow after an area is treated

Premature hairs that are in dormant state during the laser treatment will not be affected by the light rays and will continue to grow as per its regularly schedule growth cycle.

Laser treatment does not destroy hair follicles but instead send forces them to go into a dormant state where growth is halted.

Professional Laser hair removal machines used in spas and clinics sends a targeted beam of light energy on individual hair roots deep under the surface of the skin.

IPL (Intense Pulsed Light” Hair Removal Devices sends a ray of light across a wide area which is less precise but works them same over multiple treatment.

  

​If you decide to go with professional hair removal which can be pricey ( See the average cost of laser hair removal here) you can expect to have a minimum of six or more cycles of treatment to a huge reduction in hair and hair growth.

After completing a full treatment procedure which is roughly 6 sessions and can take up to 36 weeks to complete, you may still notice some hair regrowth.

Touch up treatments are usually done bi-annually to annually so you can expected to have a long grace period where your skin is silky smooth and hair free.

 
Everyone will have a different experience with the hair regrowth speed and the length at which they grow. A various number of factors ranging from skin color to hair color to the location can affect how fast your hair regrows if at all.

  

​According to the American Academy of Dermatology, Studies have shown that a 10 to 20% reduction in hair growth can be expected after each laser hair removal session.
​
The hair that does grow back is never as thick and coarse as when first treated but instead grows significantly thinner due to the lack of melanin, ultimately making them less noticeable (laser/IPL light targets melanin to slow hair growth)
