Started this about 6 months ago after noticing way more shedding in the shower. Didn't expect much but my hair feels fuller and the shedding has slowed right down. Scalp feels really clean too 👍

After my second baby my hair was falling out in handfuls 😭 nothing helped. Around 3-4 months in the shedding slowed and my roots feel so much stronger. So relieved.

Stress wrecked my hair for two years. With Kiierr the thinning noticeably slowed and new growth is coming in thicker. Wish I'd found it sooner.

Noticed thinning along my part in my late 30s and assumed it was just
aging. After using this consistently my part looks visibly narrower and my hair feels denser. Highly recommend!

Crown was getting obvious in photos and bright light. A few months in it looks fuller and I see way less hair in the drain. Easy to use too just swapped my normal shampoo.

Ask Us Anything
When will I start seeing results?
Most customers begin noticing less shedding and improved scalp health within the first 4–6 weeks. Visible hair growth and thickness typically become apparent after 90 days of consistent daily use. Hair growth is a biological process that takes time. Staying consistent is the single most important factor in seeing results.
How is Kiierr different from a regular shampoo?
Most shampoos are designed to clean hair and nothing more. Kiierr is formulated with active ingredients, including DHT blockers, follicle stimulators, and strand-strengthening proteins that work at the scalp level to address the root causes of thinning and shedding, not just the symptoms.
Is it safe for color-treated or chemically processed hair?
Yes. Kiierr Hair Growth Shampoo is gentle enough for daily use on color-treated, bleached, and chemically processed hair. The formula is free of harsh sulfates that strip color and damage the hair shaft.
Is it safe for both men and women?
Yes, these are safe and effective for both men and women. The ingredients work topically on the scalp, so they do not interfere with hormones throughout the body. Instead of altering your hormone levels, they focus on creating a scalp environment where follicles can thrive and continue producing healthier hair.
How often should I use it?
For best results, use it as your everyday shampoo. Consistent use is key — the active ingredients are most effective when applied regularly, allowing them to build up and maintain a healthy scalp environment over time.
Do I need to keep using it long term?
Yes, and here's why. Hair growth is an ongoing biological cycle, not a one-time fix. The DHT-blocking and follicle-stimulating ingredients in Kiierr work by continuously maintaining a healthy scalp environment. Once you stop, DHT levels at the scalp begin to rise again, sebum and buildup return, and the conditions that caused thinning in the first place come back with them. Think of it the same way you would a skincare routine. The results are sustained by consistency. Customers who see the best long-term outcomes are those who make Kiierr part of their daily routine indefinitely, which is exactly why autoship exists, so you never miss a day.
What is your money-back guarantee?
If you don't see thicker, fuller hair within 90 days, we'll refund you in full. See policy for details.

I started about 6 months ago after noticing more shedding in the shower. Over time my hair started feeling fuller and healthier. The shedding has slowed down and it feels thicker overall. Really happy with the progress.

Miles F.
My crown had started looking thin and it bothered me whenever I caught it in the mirror. Since using Kiierr that area looks denser and my hair feels healthier overall.
NR
Nancy R.
I went through a stressful period and started losing a lot more hair. After using this regularly my hair feels stronger again and looks fuller. The shedding has eased up.
AL
Andrew L.
More hair was falling out when I washed it and it didn't feel as full as it used to. This has really helped — stronger, healthier, and much less shedding now.
AY
Abby Y.
My hair feels fuller, softer and much healthier since I started using it. It's easy to use and just looks better overall.

Thinning around my crown was becoming obvious in photos. After a few months it looks fuller and I see a lot less hair in the drain. Stronger and healthier than before.
LR
Lainey R.
The top of my hair had gotten so thin you could see my scalp at the part. After about 4 months it looks fuller and the part isn't as wide. Really happywith how it's improving.
MZ
Marie Z.
My hair was thin and dull. After using it for a while it looks thicker, feels smoother and has a healthy shine again. So much more vibrant than before.
LH
Leo H.
Added this alongside my laser cap and the two together made a real difference. My hair feels stronger and looks fuller than it has in a long time. Even my wife noticed.
May F.
My hair gradually got thinner with age and I didn't want messy treatments. This is easy to use and my hair feels softer and a bit fuller, especially near the top.
JR
John R.
I have male pattern baldness and was already using a laser cap. Adding this shampoo sped up the progress — my hair started looking thicker much faster.

Wanted to get ahead of early thinning. So glad I did — my hair feels stronger, looks fuller and there's far less shedding when I wash and style.
