Why am I more hairy after laser? hair growth

Laser hair removal is a popular method for reducing hair growth on various parts of the body. However, some individuals may notice increased hair growth after undergoing laser treatments. This can be confusing and frustrating, but there can be several reasons why this happens.

1. Post-treatment shedding

After a laser hair removal session, it is common for the treated hair follicles to go into a resting phase. This means that the hair shafts may not fall out immediately but can take anywhere from 1-3 weeks to shed. During this time, it may appear as if the hair is growing more, but it is actually the shedding process.

2. Dormant hair follicles

Not all hair follicles are active at the same time. Some hair follicles are in a dormant phase and do not produce hair at a given time. Laser treatments can stimulate these dormant follicles, causing them to become active and start producing hair. This can lead to an increase in hair growth initially.

3. Hormonal changes

Hormonal changes can play a significant role in hair growth. Fluctuations in hormone levels, such as those experienced during pregnancy or menopause, can affect the rate and pattern of hair growth. Laser treatments may stimulate hormonal changes, leading to increased hair growth in certain individuals.

4. Incomplete treatment

If the laser treatment was not performed properly or with the right settings, it may not have effectively targeted all the hair follicles. Incomplete treatment can result in some hair follicles being unaffected by the laser, leading to regrowth in those areas.

5. Reactive hair growth

In some cases, the body’s natural response to laser hair removal can result in increased hair growth. The laser’s heat can stimulate blood flow to the treated area, nourishing the hair follicles and promoting hair growth. This reaction is temporary and should subside over time.


While it can be disheartening to experience increased hair growth after laser treatments, it is important to remember that this is often a temporary effect. Most individuals will notice a significant reduction in hair growth over time, and multiple sessions may be required for optimal results. If you have any concerns about your laser hair removal treatment, it is always best to consult with a qualified professional.
