How long after laser hair removal does Hair Fall Out?

Laser hair removal has become a popular option for those seeking to reduce or eliminate unwanted hair growth. The procedure works by targeting the hair follicle with a laser beam, damaging the follicle and preventing it from producing new hair. However, it’s important to note that laser hair removal doesn’t cause hair to fall out immediately.

Understanding the Hair Growth Cycle

To understand why it takes time for hair to fall out after laser hair removal, it’s important to understand the hair growth cycle. There are three main phases of the hair growth cycle:

  1. Anagen phase: This is the active growth phase of the hair follicle. Hairs in the anagen phase are the most susceptible to laser treatment.

  2. Catagen phase: This is a transitional phase where the hair follicle stops growing and shrinks.

  3. Telogen phase: This is the resting phase of the hair follicle. Hairs in the telogen phase are eventually shed.

At any given time, about 15% of the hairs on your body are in the anagen phase. This means that only about 15% of the hairs will be affected by a single laser hair removal treatment.

When to Expect Hair Shedding

After laser hair removal, hairs typically begin to fall out within 5-14 days. However, it may take up to several weeks for all of the treated hairs to shed. This is because not all of the hairs will be in the anagen phase at the time of treatment.

The exact timing of hair shedding may also vary depending on the area of the body being treated. For example, hair on the legs may take longer to shed than hair on the upper lip.

Factors Affecting Hair Shedding

There are a few factors that can affect how long it takes for hair to fall out after laser hair removal:

  • The type of laser used: Different types of lasers have different wavelengths and power levels. Some lasers may be more effective at killing hair follicles than others.

  • The individual’s hair growth cycle: People’s hair growth cycles vary, so some people may see results sooner than others.

  • The area of the body being treated: Hair on different parts of the body grows at different rates. Hair on the legs, for example, may take longer to shed than hair on the upper lip.

What to Expect During the Shedding Process

During the shedding process, you may notice some redness, bumps, or irritation. This is normal and should subside within a few days.

You can help to speed up the shedding process by gently exfoliating the treated area. Exfoliating will help to remove dead skin cells and promote the growth of new hair.

It’s important to note that laser hair removal is not permanent. Hair follicles can regenerate, so you may eventually see some hair regrowth. However, the regrowth is usually finer and lighter than the original hair.

Additional Considerations

Here are a few additional things to keep in mind about laser hair removal:

  • Multiple treatments are usually necessary to achieve the best results.

  • Laser hair removal is not suitable for everyone. People with very light or very dark hair may not see good results.

  • Laser hair removal can be expensive.

  • It’s important to choose a qualified laser hair removal technician.

Conclusion

Laser hair removal can be an effective way to reduce or eliminate unwanted hair growth. However, it’s important to understand that it takes time for hair to fall out after treatment. Most people will see results within 5-14 days, but it may take up to several weeks for all of the treated hairs to shed.
