Unwanted hairs are a common problem in which different light sources were developed as the treatment of choice. Alexandrite laser, diode laser, and intense pulsed light (IPL) were clinically used for this purpose with long-term scarce comparative results. The objective of the study was to compare the clinical efficacy, complications, and long-term hair reduction of alexandrite laser, diode laser, and IPL. Clinical trials on 232 persons using diode, alexandrite, laser and IPL were conducted. The… 

Effects of the 810-nm diode laser on hair and on the biophysical properties of skin

The findings of this study showed that the diode laser can perform a significant reduction in the hair amount without significant epidermal damage, at least for a short period.

Removal of unwanted hair: efficacy, tolerability, and safety of long-pulsed 755-nm alexandrite laser equipped with a sapphire handpiece

Due to the difference in refraction coefficients between air and the corneal epithelium, irradiation of the skin with a light source can lead to reflection of the energy and its leakage to the skin

Efficacy of long pulsed Nd:YAG laser in the treatment of hirsutism

The results of this study support safe and effective use of long-pulsed, 1064 nm Nd:YAG laser for hair removal in Indian patients.

Laser and intense pulsed light hair removal technologies: from professional to home use

The principles underlying laser and IPL technologies are outlined and an evidence‐based assessment of the short‐ and long‐term efficacy of the different devices available to the practising dermatologist is undertaken and the efficacy and human safety implications of home‐use devices are discussed.

Comparison of Alexandrite and Diode Lasers for Hair Removal in Dark and Medium Skin: Which is Better?

Both lasers were suitable in LHR for dark skin types, but the diode laser was better than the alexandrite laser because the former could penetrate deeper into the dermis layer.

Photoepilation of Unwanted Hair Growth

Patients should be preoperatively informed of the expected treatment outcome from laser and IPL hair removal procedures in order to gain realistic expectations.

Intense Pulsed Light for Skin Rejuvenation, Hair Removal, and Vascular Lesions: A Patient Satisfaction Study and Review of the Literature

No difference regarding satisfaction was recorded in this study, but complications were more frequently encountered after rejuvenation, and the findings of this study are useful when discussing IPL treatments with patients considering IPL procedures.

Within-patient right-left blinded comparison of diode (810 nm) laser therapy and intense pulsed light therapy for hair removal

Both laser and IPL reduced the hair count substantially; laser vs control was significant at P’= 0.028, but IPL vs control had P =‬0.13, suggesting that more subjects or more treatments were required if statistical significance were to be achieved.

Paradoxical Hypertrichosis After Laser Therapy: A Review

Par paradoxical hypertrichosis is a rare side effect of laser hair removal; the pathogenesis of this event remains widely unknown and the authors recommend further large‐scale studies to investigate this effect.



Hair removal with an 800-nm pulsed diode laser.

The 800-nm diode laser is an efficient and safe technique for hair reduction and adverse pigmentary effects occur, but are transient.

Laser‐Assisted Hair Removal in Asian Skin: Efficacy, Complications, and the Effect of Single Versus Multiple Treatments

Although Asian skin can be effectively treated with a cooled, long-pulsed alexandrite laser, complications do occur, and the benefit of multiple treatments is determined, the value of test patches before laser treatment is evaluated.

Laser Hair Removal: Long‐Term Results with a 755 nm Alexandrite Laser

The 3-msec cryogen cooling-equipped alexandrite laser can safely and effectively achieve long-term hair removal in patients with skin types I–V, and the best results are achieved in untanned patients withSkin type I–IV.

Alexandrite Laser Hair Removal is Safe for Fitzpatrick Skin Types IV‐VI

The long‐pulsed alexandrite laser is safe for hair removal in darker skin tones and there was no relationship between skin reaction and the incidence of complications in this study.

While long-term hair reduction can be obtained in most patients after a series of laser treatments, partial hair regrowth is typical within 6 months, suggesting the need for additional treatments to improve the rate of permanent hair removal.
