How long to set laser treatments for back of neck hairline?

Question

I have had laser hair removal on the back of my hairline. After the first treatment, I thought it was permanently gone (no hair growth for at least two months). The same happened after my second and third treatment. But the amount of hair that is growing back seems to be similar thickness and only slightly slower regrowth. Is it okay to set my laser hair removal treatments only at the times when I have regrowth? (i.e. two months apart, or does it need to be a very specific period of time?).

It seems as if you are getting desired results which is gradual thinning of the unwanted hair. It could be that for you, treatments at 8 weeks is in line with the way that your hair grows. Everyone is different and while we usually set treatments 4-6 weeks apart, it could be that your hair growth is at a slower pace. Speak with your clinic about customizing your treatments.

Thank you for your question. There is not a time frame for laser hair removal that fits for everyone. Although, it does seem you are getting desired results. It is possible that for you, treatments spaced 8 weeks apart is in line with the way you hair grows. While we typically space treatments 4-6 weeks apart, it is possible that your hair grows a much slower pace. I recommend speaking with your treating physician about customizing your treatments. Best of Luck!

Laser hair removal works best on hair that is in the anagen or growth phase. During the phase, hair follicles have more pigment than at other times, making them more susceptible to laser energy. At any given time, almost 90% of your hair is in this phase but because not all of your hair is in this phase at once, it requires several treatments to achieve maximum results.  . On average, three to five sessions are necessary to achieve maximum results, after which you should experience several months of almost complete hairlessness. Overall, you can expect an 85% permanent reduction of hair in the treated area. I recommend getting a in person consultation with a board certified dermatologist.

Thanks for your question and your guess is correct.  There isn't a timeframe that is correct for everyone.  We start off with general guidelines, but customize it for each patient.  First, you have to understand how LHR works.  Hair removal lasers are targeted to the melanin in the hair follicle.  The laser energy follows the hair shaft (with pigment) down into the follicle, heats the follicle rendering it unable to produce another hair.  If hair is not actively growing or if you have waxed or plucked the hair shaft out of the follicle, there isn't a path for the laser to follow and any treatment is pointless.  We coach our patients to delay treatment until they have a significant amount of hair growing in the treatment area.  Best of luck.
