Will Hair Grow Back After Diode Laser?

Jul. 17, 2025

Overview of Diode Laser Hair Removal Procedure


With diode laser hair removal, hair follicles are treated with concentrated beams of light, damaging their capacity to regrow. Different from shaving or waxing, which only offer temporary relief, diode laser hair removal works by wrenching the follicle's growth cycle from the very root. The secret lies in precision of the wavelength. Razorlase employs an 808nm diode which is considered the gold standard for safety vs effectiveness balance as it penetrates the follicle without damaging skin. 


Is Hair Regrowth Possible After Diode Laser Treatment  


The succinct answer is: hair mostly does not grow back. Devices like Razorlase are designed with the intention to permanently reduce hair growth, as opposed to simply removing hair. Clinical data indicates about 90% of subjects report 70-80% reduction in hair growth after 6-8 sessions. Any regrowth that occurs tends to be finer, lighter, and more sparse. This is due to the fact the laser is only active on follicles and as time progresses, fewer follicles remain 'active' or 'awake'. Optimal results require consistency, skipping sessions allows follicles to recover. 


How Razorlase Stands Out With 808nm


Not all diode lasers are the same. Razorlase's 808nm diode sincoheren wavelength is specifically designed to be multifunctional. Unlike shorter wavelengths (for example laser 755nm), 808nm is safe on all skin tones as it avoids the surface melanin of the skin.

This truly shifts the paradigm: Razorlase not only refrains from burning or discoloring darker skin while treating pigmentation issues, it also laser precisely avoids these risks.  


Certifications You Can Trust: FDA, TUV, ISO 13485  


Safety concerns are always paramount especially with devices that utilize lasers. Razorlase is recognized for FDA approved laser clearance, TUV Medical CE certification, and ISO 13485 compliance—these, alongside others, make Razorlase's safety claims robust and thorough. These are not mere labels; Razorlase beyond these claims is also dual shielded undergoing regular audits confirming energy output stability and optimized performance of critical comfort cooling systems. 


How Razorlase Compares to Other Hair Removal Methods  


808 hair removal diode laser technology surpasses IPL (Intense Pulsed Light) and electrolysis in treatment speed and requires less frequent sessions. IPL is more scattershot and less precise while electrolysis is painstakingly slow by only focusing on one follicle. Razorlase strikes the balance: its 808nm wavelength delivers focused energy, treating multiple follicles with each pulse, making it superb for large areas such as legs and backs.  


What to Expect During and After Treatment 


Razorlase treatments are not only effective but also time efficient; underarms and legs take less than 5 and 20 minutes respectively. Expect to feel minimal discomfort; a rubber band snap at most. Redness post treatment is expected but subsides within a few hours.

Most individuals resume their regular routines right away. Over 6-8 sessions (4-6 weeks apart), there is a marked reduction in density of hair. For ongoing maintenance, touch-ups may be necessary on an annual basis, but a lot of clients appreciate a permanent reduction after the first course.   


Why Razorlase is Preferred by Professionals  


Razorlase is trusted by clinics for its patient satisfaction and reliability. Its metal medical-grade casing together with a rugged laser tube guarantees several years of reliable hair removal performance. Additionally, its fillable spot size of 10mm × 12 mm is suitable for both large and small regions. As with most tools, the hair skin removal laser for professionals has no training requirement, integrates into most practices effortlessly, and has no downtime. Only results matter.
