Sorry, you mean she (your client) checks in three to four years for new hair growth from untreated or untouched hair follicles?

The client doesn’t do anything. Some will develop sporadic hair growth in the future, most do not. The ones that do, have the following options: do nothing, use temporary methods at home, or start electrolysis. It’s that simple.

Yeah I mean her client comes in every three to four years to see if there is any NEW growth from different hair follicles / dormant hair follicles “awakening” and to treat them if there is. What I meant was sometimes NEW hair growth happens after the successful completion of the treatment maybe due to hormones, certain medications or disorders.

Well, I’m a bit confused. There is another opinion about that: https://hairtell.com/forum/t/laser-rebound-years-later-to-geeeza-dpp-and/38383
Josefa pointed out one case in which hair regrowth took place more then a year later! It was laser, but damage is damage…
Marat, that is probably hairs that were “stunned” into dormancy and can come back years later. I have heard lasers can do that. I was wondering if Electrolysis can also do that, but it appears not. Also lasers can induce or stimulate new hair growth.

Come to think of it, electrolysis is much stronger than laser, so its impact has to be stronger. And if after powerful electrolysis “weakened but alive” hairs return in several weeks, how is it possible for laser to send hairs into dormancy for several years?
It seems that electrolysis doesn’t leave any dormancy; it kills all hair. Or not?
Who can say how long “dormancy period” (whatever reason) can take? Especially on males? Maybe testosterone decreases that period? FTM guys on HRT grow beard and body hair in 1.5-2 years (more or less, to my knowledge).
Lasers REDUCES Hair, NOT destroys hair at least not all of it, unlike Electrolysis. They can also stimulate new hair growth, unlike Electrolysis.
It’s so confusing how they consider laser to”permanently reduce” hair. From my experience if prevented any hair growth for happening for roughly two years from last laser appointment (total of 5 laser appointments) what seems odd to me is how they figure the laser is capable of permanently reducing hairs which my interpretation of that is it can permantly kill hairs but only some of them. If it’s capable of killing some hairs then how come it couldn’t eventually kill all of the hairs? Hypothetically assuming the skin could handle the laser again and again ( which I highly doubt since it’s not exactly good for the skin) am I misunderstanding the wording they use? Maybe they mean reduce permantly for a given amount of time or what but either way I think the wording used by the fda is telling of effectiveness as far as it achieving permanency. The phrase just seems very ambiguous to me. Like this is your reading this and have had a negative experience, like I have with laser
Here is the FDA’s definition of permanent hair reduction: “Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs re-growing after a treatment regime, which may include several sessions.The number of hairs regrowing must be stable over time greater than the duration of the complete growth cycle of hair follicles, which varies from four to twelve months according to body location. Permanent hair reduction does not necessarily imply the elimination of all hairs in the treatment area.”

You are correct that laser kills some hairs but not others. It is due to how laser works. The light it emits is a specifically chosen frequency that’s absorbed mostly by the pigment in the hair. The darker the hair and the bigger the root, the better the chance of killing it. But many people have a mix of hair colours, so the darker one will be killed, but not the lighter. Often the hairs treated are in different stages of growth; the growing ones have deep dark juicy roots, but the resting ones have shallow dry white salt grains at the end of them. The former would treat well and the latter won’t get killed by the laser.
