Description
Formulated with over a dozen active ingredients, including DHT blockers, scalp stimulators, and hair-strengthening keratin, Kiierr Hair Growth Shampoo goes far beyond cleansing to treat thinning hair at its source with every single wash.
Consistent long term use is what separates people who see real, lasting results from those who don't. Your follicles need continuous support to stay healthy and productive.
Ingredients
Ginkgo Biloba & Kigelia Africana — Boost scalp circulation to deliver oxygen and nutrients to the follicles and extend the hair's growth phase.
Clary Sage, Cinnamon & Zinc PCA — Target DHT, the hormone behind follicle thinning, while cleansing the scalp of buildup and excess oil.
Hydrolyzed Keratin & Panthenol (Vitamin B5) — Rebuild and reinforce the hair shaft, adding strength, thickness, elasticity, and moisture.
Jojoba & Wheat Germ Oil — Nourish the scalp and protect follicles from oxidative stress, with Vitamin E to guard against premature shedding.
Collagen Amino Acids & Hydrolyzed Glycosaminoglycans — Replenish and deeply hydrate, leaving hair fuller and smoother.
Other Ingredients: Water, Disodium Laureth Sulfosuccinate, Propylene Glycol, Cocamidopropyl Betaine, Cocamide MEA, Sodium Olefin Sulfonate, Acetamide MEA, Glycerin, Sorbitol, Cocoyl Sarcosine, Polysorbate 20, Tocopherol, Tocopheryl Acetate, Polysorbate 80, Fragrance, Diazolidinyl Urea, Iodopropynyl Butylcarbamate, Tetrasodium EDTA, Ext. Violet 2, Citric Acid, PEG-150 Pentaerythrityl Tetrastearate, PEG-6 Capric/Caprylic Glycerides.
Instructions
How to Use
Wet your hair thoroughly with warm water, then apply Kiierr Hair Growth Shampoo directly to the scalp and roots. Gently massage in circular motions for 1-2 minutes to stimulate the scalp and work the formula into the hair follicles, then distribute through the lengths of your hair. Leave on for up to 5 minutes then rinse thoroughly with warm water.
Each bottle contains 8 oz of shampoo. How long a bottle lasts and how many you'll need per month depends on your hair length & how often you wash.
For Best Results
Consistent daily or near-daily use is key. Hair growth is a gradual process and clinical results are typically seen after 90 or more days of regular use. We recommend starting with a supply that covers at least three months to give the formula time to work.

I'd tried every shampoo on the market before Kiierr and honestly expected nothing different. By month 3 my hairline had visibly stopped receding and my scalp felt healthier than it had in years.

After having my second baby my hair was falling out in handfuls and nothing was helping. After around 3 or 4 months the shedding slowed significantly and my roots felt stronger.

Stress had taken a serious toll on my hair over the past 2 years and I could see my scalp through my crown. With Kiierr the thinning had noticeably slowed and new growth was coming in thicker.

I started noticing thinning along my part in my late 30s and assumed it was just aging.After using this shampoo consistently my part looked visibly narrower and my hair felt denser overall.

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.

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.

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

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.

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.

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.

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.

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.
