First laser treatment, will hair that's fallen out regrow?

Hi, i need a small information. One week has passed from my first laser treatment. Hair started to fall out, fallen hair means it wont grow back ever again? Is that correct?

Will Hair that's Fallen out Regrow?

It is too early after laser hair removal treatment to see results. Remember it takes 6-9 sessions of laser treatment to reduce 70%-90% of the hair. This is because not all hair is in its active growth phase. Keep up with your treatments to see best results.

Hair fallen off after laser: will it regrow?

One needs series of laser sessions for effective reduction of overall growth of hair. Remember I said "reduction" and not "removal". You will also need maintenance sessions few times a year, after a series of 5-7 initially. Don't expect that one laser session will be all that would be needed.

Hair fell out after laser treatment, is it gone for good

This is probably not the case. The treatments need to be done in a series of at least 6 to get good lasting results. Also touch up are needed at least every 6 months. Don't look at results only after one treatment.

Laser hair removal

Hair has 3 stages of growth - active, non-active or dormant, and transitional.  Laser hair removal acts on the pigment in the hair follicles that are in the active stage of growth (and some of the those in the transitional stage as well).  Not all the hair is in the same stage of growth at any one time, that is why multiple treatments are recommended for optimal results during hair removal treatment.  So, in answer to your question, the hairs that are actually falling out are probably the ones that were in the active stage of growth when you were treated, and will not come back.  However, there will be some hair regrowth in a couple of weeks as the hairs that were in the dormant stage begin to become active again and grow.  You should notice less regrowth after each treatment.
