What Happens If You Don't Shave Before Laser Hair Removal

Laser Hair Removal has become a popular method for achieving long-lasting hair reduction and smoother skin. However, there are specific guidelines to follow before your Laser Hair Removal session to ensure the best possible results. One of the most crucial preparatory steps is shaving the treatment area. But what happens if you don’t shave before Laser Hair Removal? In this article, we will explore the importance of shaving before your laser session and the consequences of not doing so.

Why Shaving Is Necessary Before Laser Hair Removal

Effective Targeting Of Hair Follicles:

Laser Hair Removal works by directing a concentrated beam of light into the hair follicles. The pigment in the hair follicles absorbs this light, which then damages the follicles, inhibiting future hair growth. When you don’t shave before your session, the laser’s energy is absorbed by the visible hair above the skin’s surface, making it less effective in reaching and damaging the hair follicles.

Preventing Surface Burns:

If there is hair on the surface of the skin during a laser hair removal session, it can absorb the laser energy and potentially cause surface burns or discomfort. Shaving ensures that there is no hair above the skin to interfere with the treatment.

Enhancing Comfort:

Shaving before laser hair removal not only improves the effectiveness of the treatment but also enhances your comfort during the session. It minimizes any potential stinging or burning sensations caused by the laser energy being absorbed by hair on the skin’s surface.

Consequences Of Not Shaving Before Laser Hair Removal

If you choose not to shave before your laser hair removal appointment, several consequences may arise:

Reduced Effectiveness:

The laser may not effectively reach the hair follicles, resulting in suboptimal results. You may require more sessions to achieve the desired hair reduction, and the process could take longer overall.


Not shaving can lead to discomfort during the treatment, as the laser energy may be absorbed by the visible hair on the skin’s surface, causing stinging or burning sensations.

Increased Risk Of Burns:

Hair on the skin’s surface can absorb laser energy and potentially lead to burns or skin irritation.

Inconsistent Results:

Without shaving, the treatment may yield inconsistent results, with some areas responding better than others. This can lead to uneven hair reduction.

Wasted Time & Money:

Ineffective sessions due to lack of shaving may result in wasted time and money, as you may need additional treatments to achieve your desired results.


Shaving before Laser Hair Removal is a critical step in ensuring the effectiveness, safety, and comfort of the procedure. It allows the laser to target the hair follicles beneath the skin’s surface without interference from visible hair. Failing to shave can lead to reduced effectiveness, discomfort, and the risk of burns. To get the best results from your Laser Hair Removal sessions, be sure to follow the pre-treatment guidelines provided by your licensed practitioner, which typically include shaving the treatment area beforehand.
