Dr. Chettawut’s Recommendations for Genital Hair Removal in SRS Patients

One of the primary concerns for Sex Reassignment Surgery (SRS) patients is the potential for hair growth inside the vagina post-surgery. This article addresses this concern and provides guidance based on Dr. Chettawut’s expertise.

No Hair Growth with Dr. Chettawut’s Non-Penile Inversion Technique

Dr. Chettawut’s non-penile inversion technique utilizes a hair-free skin graft, ensuring no hair growth inside the vagina post-SRS. This method eliminates the possibility of hair growth within the vaginal canal. For more details on this technique, visit Dr. Chettawut’s skin graft technique page.

Hair Growth in External Genitalia and Vulva Area

While the skin graft used for the vagina remains hair-free, the original skin of the external genitalia (penile and scrotal skin) may contain hair roots. This can lead to hair growth in the vulva area (the outer part of the female genitalia) after surgery.

Genital Hair Removal: Recommendations and Precautions

Dr. Chettawut advises against genital hair removal (either via electrolysis or laser) on the penis or scrotum before SRS. These methods can cause post-inflammatory reactions, resulting in thicker or less elastic skin, which is not ideal for SRS. The skin used in the surgery should be thin and pliable, and any procedure affecting skin quality should be avoided.

Perineal Hair Removal Before SRS

The only area where Dr. Chettawut allows pre-SRS hair removal is the perineal skin (the skin between the anus and the base of the scrotum). If you have significant perineal hair, it could lead to hair growth around the vaginal opening post-SRS. Dr. Chettawut recommends considering perineal hair removal to prevent this.

Timing for Perineal Hair Removal

If opting for perineal hair removal before SRS, it should be completed at least four months prior to surgery. Alternatively, you can wait and decide on hair removal six months after SRS if necessary.

Hair Removal Methods: Electrolysis and Laser

Laser Hair Removal

This method uses pulsating light beams to target the melanin in hair follicles, temporarily stopping hair production. It is suitable for those with light skin and dark hair.


This method uses electric energy to permanently destroy hair follicles. It is effective for all skin and hair colors, as it targets the follicle itself, not the pigment. A tiny needle is inserted into the skin, delivering a low-level electrical pulse to destroy the follicle.

Consulting a Licensed Technician

For both laser hair removal and electrolysis, it is crucial to consult a licensed technician or specialist trained in these procedures to ensure safety and effectiveness.
