Hormones & Laser Hair Removal: Why Chemistry Dictates Your Results
At Luminier Laser Aesthetics in Leighton Buzzard, we pride ourselves on a rigorous, medical-grade approach to permanent hair reduction. However, achieving flawless, smooth skin isn’t just about using any technology – it is deeply tied to your body’s internal chemistry and using the correct medical equipment. If you have ever wondered why hair grows back unexpectedly, why certain conditions like PCOS complicate hair removal, or how your skin type and hair colour factor into the equation, biology holds the answers. Here is exactly how hormones affect your hair growth, and what that means for your custom laser journey with our advanced British-built technology
The Science: How Hormones Trigger Hair Growth
Every hair follicle on your body passes through three distinct phases: Anagen (active growth), Catagen (transition), and Telogen (resting). Laser hair removal works by targeting melanin (pigment) in the hair root exclusively during the Anagen phase,
Your endocrine system acts as the master switchboard for these phases. Specifically, a group of hormones called androgens (which include testosterone) dictate the
- When androgen levels spike, soft, barely visible "vellus" hair (peach fuzz) can morph into coarse, dark "terminal" hair.
- Hormonal shifts during pregnancy, menopause, or periods of high stress can awaken dormant hair follicles, triggering brand-new growth cycles long after you thought your hair was gone.
The PCOS Factor: Managing Hirsutism
or individuals living with Polycystic Ovary Syndrome (PCOS- PMOS), an overproduction of androgens frequently causes a condition known as hirsutism – excessive
What it means for your laser results:
If you have PCOS, laser hair removal is highly effective, life-changing, and completely safe, but your treatment plan requires a realistic, clinical approach:
Management vs. Cure
Laser destroys existing follicles, but your hormones will continuously try to stimulate new ones.
Session Frequency
Clients with PCOS typically require more initial sessions to achieve complete clearance.
Long-Term Maintenance
While standard clients might need a top-up session once a year, PCOS clients generally require touch-ups every few months to keep new, hormonally triggered growth at bay.
Skin Type Suitability: Power of the Polaris Medical Nd:YAG (1064nm)
Historically, laser hair removal was only effective for individuals with fair skin and dark hair. Deep or rich skin tones faced significant risks of burns or pigmentation damage from older laser technologies. Today, modern medical aesthetics have completely
At Luminier Laser Aesthetics, we have invested in the premier gold standard for universal hair removal: the Polaris Medical Long Pulsed Nd:YAG 1064nm Laser.
How it works
The 1064nm wavelength is uniquely deeply penetrating. Because its nlight absorption by melanin in the skin surface is very low, it safely bypasses the epidermis entirely. Instead, it drives all its heat energy
straight down to the root of the hair follicle.
Unmatched Safety
This makes our Polaris Nd:YAG the safest possible choice, explicitly engineered to treat all 6 skin types on the Fitzpatrick scale – from fair skin to deep, dark black skin tones – with zero risk of skin damage.
The Ultimate Boundary: Light, Blonde, Red, & Grey Hair
While modern lasers like our Polaris Nd:YAG have mastered all skin tones, they still face a biological hurdle when it comes to hair colour. Because lasers rely entirely on melanin to channel heat down to the root, the amount of pigment in your hair dictates your success.
Dark Hair (Brown/Black)
Contains high amounts of eumelanin, making it the perfect target for the laser.
Blonde & Red Hair
Contains pheomelanin, a lighter pigment that is significantly harder for standard lasers to "see"
White & Grey Hair
Contains zero melanin. Because the hair shaft is completely devoid of pigment, the laser light passes straight through without generating the heat needed to destroy the follicle.
What it means for your results
If your unwanted hair is white, grey, or very pale blonde, laser hair removal will unfortunately not be effective. If you have a mixture of dark and grey hairs, the laser will successfully eliminate the dark hairs, but the grey hairs will remain.
