The Kiierr laser cap gave me a piece of myself back & I couldn't be more grateful.
After giving birth I experienced postpartum hair loss, which was really hard to deal with. But after just a few months of using Kiierr, I noticed less shedding & even regrowth in the areas that had thinned out. Getting my hair back has been such a huge confidence booster post baby.

Can Kiierr regrow hormone-related hair loss?
Yes. Kiierr’s laser cap uses gentle therapeutic light that stimulates follicles at the cellular level. When hormone changes cause hair to thin many follicles slow down but are still alive.
The light helps reactivate those dormant follicles and can increase hair density over time. It does not alter your hormones but supports the growth cycle so more hairs are in the active growth phase.
Will it work if my hormones fluctuate?
Yes. Hormone fluctuations during perimenopause and menopause can disrupt your hair growth cycle and cause shedding or thinner hair. The Kiierr Laser Cap supports follicles regardless of where you are in your hormonal journey.
Consistent use gives hair follicles the energizing signal they need which can help reduce shedding and strengthen what you have even if hormones are still changing.
Does it help with perimenopause shedding?
Yes. Perimenopause shedding happens because follicles spend more time in the resting phase. The laser cap helps shorten that resting phase so more hairs move into growth.
Many women see less daily shedding and a fuller look when they make the cap part of their regular hair care routine.
What if I don’t see results?
Kiierr offers a 7 month growth guarantee. If you don’t see results and you’ve used the cap as directed, you can request a refund. See full details here. We stand behind the science and thousands of successful customer outcomes, but we also believe in risk free support for your hair journey.
Will this help with menopause hair thinning?
Yes. Thinning during menopause is very common and is mainly a result of slower hair growth cycles. Kiierr’s technology supports follicle health which can increase hair thickness and density. It is not a hormone treatment but it helps follicles that are weakened instead of gone forever.
Is the Kiierr Laser Cap safe for long term use?
Yes. Kiierr uses low level laser light which is non invasive and has a solid safety profile. It does not use heat or cause damage to the scalp. Many women use the cap for years as part of their ongoing hair health regimen.
When will I see visible regrowth?
Most women begin to notice changes around 8-12 weeks when using the cap as recommended. Hair growth is a slow natural process so visible regrowth often becomes more noticeable between months 4 and 7. Results vary with individual biology consistency of use and other factors like overall health.
Do I need to stop other hair products or treatments?
No. You can continue your current shampoo conditioner and scalp care products. The laser cap works well alongside gentle growth enhancing products. Avoid overprocessing with harsh chemicals or excessive heat styling as they can stress hair but normal styling is fine. The cap is designed to complement your existing routine not replace it.
