What skincare to avoid after laser

How Long Does Laser Hair Removal Last?

If you are suffering from unwanted hair and are looking for a long-term solution, then you must have already heard about laser hair removal and its effectiveness. However, considering its popularity, one major question still lingers: how long does laser hair removal last? Knowing the duration of laser hair removal results should help you figure out if this treatment is worth it.

What exactly happens during a laser hair removal procedure?

Laser hair removal uses light energy that is highly concentrated and focused on the pigment that exists in hair follicles. When the laser is focused on the follicle, it becomes damaged, which lessens the follicle’s ability to produce hair. If properly treated multiple times, these follicles become dormant, atrophy and in some patients, can lead to significant or even total hair loss over time.

Do you have to worry about unwanted hair growth after laser hair removal?

A lot of people prefer to use the term “permanent”, but its depictions a slightly misleading outlook. With laser hair removal, there is a long-term reduction effect for hair, but that does not mean complete hair elimination. The greatest effects of the treatment can be seen on people with dark hairs and pale complexion. The laser targets the pigment, and so, the more of it there is, the more effective the treatment will be. For most, the effects can last from several months to multiple years based on factors like:

  • Type of Hair: Darker type of hair, when compared to lighter hair responds better to laser hair removal.
  • Type of Skin: Individuals with light hair and darker skin are likely to see improved permanency of results.
  • Treatment area: Treatment may be more effective on the legs or back than hormonal areas such as the face.

How Long Does It Last?

When a treatment regimen is completed (typically 6-8 sessions about once every few weeks), a large proportion of the population demonstrates decreased growth of hairs. After this cycle of treatment, it is reasonable to say:

  • Reduced Hair Growth: As hair grows back, it tends to be thinner, finer and not so apparent. Not much hair will have occupied the area for some months or even several years.
  • Touch-Up Sessions: It is also important to note that laser hair removal may be effective in some patients for an extended period of time, but some maintenance every 6-12 months may be needed to maintain the result particularly in the face and the armpit where there are a lot of hormones.

Factors That Influence Longevity

There are a number of different factors which may affect how durable the results of the laser hair removal treatment are:

  • Hair Growth Cycles: These cycles are in relation to the hair growth phase in which laser hair removal takes place. Treatment is effective in catching hair that grows actively meaning multiple sessions are needed.
  • Hormonal Changes: Changes in the body (due to pregnancy for example, or menopause, or other medical conditions) that affect the hormonal balance can lead to hairs growing in parts that have previously undergone laser treatment.
  • Skin Care Routine: As part of your aftercare, use sunblock and stay away from harsh skin treatments to prolong the effects of your laser hair removal for a long time.

Conclusion

It is important to highlight that laser hair removal is not a complete solution for unwanted hair, but it does provide long-lasting hair reduction. Most people manage to have smooth and hairless skin for months or even years with proper care and occasional touch up. If you are thinking of going for laser treatment for your hair removal, make sure you consult a licensed technician who is experienced and can customize a plan based on your skin type, hair type, and what look you hope to achieve.
