Why Is My Hair Growing Back Two Days After Laser?

If you’ve recently had laser hair removal and noticed hair growing back just a couple of days later, you might be wondering: “Did the treatment even work, why is my hair growing back two days after laser?” Don’t worry—this is a completely normal part of the process, and it doesn’t mean the laser wasn’t effective. Let’s break it down.

How Laser Hair Removal Works

Laser hair removal London treatments target the pigment (melanin) in your hair follicles, heating them to a point where the follicle is damaged and can no longer grow hair. However, not all hair is in the same growth stage at the time of treatment. Hair grows in cycles—anagen (active growth), catagen (transitional), and telogen (resting). The laser only works on hairs in the anagen phase, which is why multiple sessions are needed.

What’s Actually Happening?

The “hair” you’re seeing a few days after treatment isn’t necessarily new growth. It’s often shedding hair being pushed out of the follicle. This is a sign that the laser successfully treated the follicle, and it’s clearing out the dead hair shaft. This shedding process, also called “peppering,” can last anywhere from a few days to a couple of weeks.

In some cases, it may feel like the hair is growing back because it’s breaking through the skin. But rest assured, this hair is on its way out. If you gently exfoliate the area, you might notice it loosens or falls out more quickly.

Why Does It Feel Like Hair Is Growing Back?

If some hair does seem to grow back, there are a few explanations:

Untreated Hairs: Not all hairs were in the active growth phase during your session, so some weren’t affected by the laser. These will continue to grow until they’re treated in a future session.

Shaving Before Treatment: Since you’re typically asked to shave before a laser session, it can be hard to tell which hairs were actively treated. Hair that wasn’t in the growth phase will naturally grow out until the next session.

Hormonal Factors: For some people, conditions like PCOS (polycystic ovary syndrome) or hormonal changes can stimulate new hair growth even during laser treatments.

What Can You Do?

Here are some tips to manage this stage:

Exfoliate Gently: Use a mild exfoliating scrub or a soft washcloth to help the shedding process along. Avoid anything too harsh, as your skin might be sensitive after laser treatment.

Be Patient: It takes an average of 6 to 8 sessions to see significant, long-lasting results. Hair becomes finer and grows slower with each session.

Avoid Waxing or Tweezing: These methods can disrupt the hair growth cycle, making it harder for the laser to target the follicle during future sessions.

Stick to Your Schedule: Ensure you’re attending your appointments at the recommended intervals (usually 4 to 6 weeks apart). This timing aligns with the hair growth cycle, maximising the laser’s effectiveness.
