How Much Hair Should Fall Out After Session of Laser Hair Removal (Bikini)?

I've had one session 2 weeks ago. It seemed like a really quick session. I've had a few hairs fall out - once they fall out, are they permanently gone? Do hairs continue to fall out over time, and I won't really know how effective the treatment was for weeks yet? Or should all the hair fall out the first time, and then a portion regrows, and that's when you do your next session?

Laser hair removal and fall out

Appropriate laser hair removal involves shaving of the hair so that there is no hair shaft sticking high above the surface, otherwise too much energy may be absorbed by the epidermis and the skin could get burned. Therefore, within two weeks you shouldn't see hair fall out because it was already shaved off. The hair that grows out will take some time to do so and will shed probably without your seeing it.

Laser Hair Removal Requires Several Treatment Sessions

In general, two or more treatments are required at each site to achieve permanent hair removal. The laser is only effective when the hair follicle is in its active growth phase. Repeat sessions will be necessary to treat those follicles when they re-enter the growth phase.

Hair removal treatments require multiple treatments

Don't expect to have all the hair fall out after just one laser or IPL hair removal session. Multiple treatments are required because hairs cycle and only actively growing hairs are effected with each treatment. Expect to do at least six treatments about 3-4 weeks apart.

Hair fallout after laser hair removal

All the hair that was effectively treated in that laser hair removal session should fall out around the same time. If you had a short treatment session and are now only seeing a little bit of hair fallout, then you may have correctly assumed that your treatment was not comprehensive. Your sessions should be timed according to the type of laser being used. Also, keep in mind that blonde, red, and gray hair generally does not respond to laser hair removal, so you won't see... more
