Description
Kiierr’s DHT Blocking is specially formulated to fight thinning hair at the source while keeping your scalp refreshed and balanced. It combines nourishing botanicals, essential oils, and science-backed actives to gently cleanse, hydrate, and strengthen your hair with every wash. Designed for both men and women, it supports thicker, fuller, and healthier-looking hair over time.
How It Works
Hair thinning often begins when DHT (a hormone byproduct) binds to hair follicles, weakening them and slowing growth. The shampoo deeply cleanses the scalp, removes buildup, and delivers natural DHT-fighting ingredients that target the root cause of thinning.
Ingredients & Instructions
The shampoo combines ginseng and ginkgo biloba to energize the scalp, clary, cinnamon, zinc PCA, green tea, and kapilarine to help block DHT and deeply cleanse the scalp and hair, keratin and panthenol to strengthen strands, and nourishing jojoba and wheat germ oils to hydrate and soften hair.
To Use: Apply the shampoo to wet hair and gently massage into the scalp and roots for one to two minutes before rinsing thoroughly. Leave on for two to three minutes, or up to five minutes for deeper hydration, then rinse well.

Over 100k Users Trust Kiierr to Restore Their Hair
Real customer before-and-afters showing how Kiierr Laser Caps and supplements helped restore their hair.
It’s a worthwhile investment!
I started using my Kiierr cap & shampoo almost 4 years ago at 63. After the first 6 months or so, I noticed that there was less hair caught by my shower drain strainer than in the past. My temples and the thinning hair on my crown have filled in.
Frank L
My hair is a lot thicker!
Thicker hair on my crown has been the most noticeable change since starting with Kiierr products. Over the last several months, my hair has visibly thickened, especially in areas that were previously thinning.
Mark R
My hair is thicker than it’s ever been!
I suffer from hormone-related hair loss. It was devastating to see my hair become thinner & thinner. I have been using Kiierr for 10 months now. At first I was skeptical (was this too good to be true?), but I was astounded when I started seeing growth after 6 weeks!
Denise C
My hair is thicker and fuller!
After contracting COVID, I experienced severe hair loss. I tried the Kiierr Laser Cap and after 5-6 weeks, new hair began growing on my bald spots. By two months, my hair became thicker and fuller. After three and a half months, I was thrilled with the results and highly recommend!
Marsha W
Nothing worked until Kiierr!
After spending 10 years trying other hair growth products, I heard about the success of laser therapy after researching. As you can see, during the 3 year process of using the Kiierr Hat, I could see remarkable results after only 6 months.
James R
The Kiierr Cap really helped!
I've always had thin hair in the crown but 3 months after having Covid, my hair started coming out in handfuls. The Kiierr cap was what helped along with Kiierr’s shampoo, conditioner and biotin.
Karla P
Recommended by my doctor!
I suffered from a mold exposure that caused excessive hair loss, and this treatment was recommended by my doctor. With continued use of the cap, the vascularity of my scalp has improved. The cap has helped significantly in promoting new hair growth.
Jenna P
Reversed my menopause thinning!
Noticeable menopause thinning led me to try Kiierr's hair cap. After using it consistently three times a week for several months, I began to see real results. My hair started growing back. Even my friends & hair stylist noticed the improvement!
Karen N
I love my Kiierr cap!
I use it faithfully and have really seen a difference in my hairline. It was receding on the sides, temples and front, but has definitely stopped and is actually filling in with hair! I would definitely recommend a Kiierr Cap
Lisa L
Kiierr saved my hair!
At 65, my hair started falling and I was nearly bald. I didn’t want a transplant and couldn’t see a doctor during COVID. I tried Kiierr, and it truly helped. Thickened my hair and stopped the loss. I recommend it to everyone facing hair loss.
Jorge V
This cap made me look younger!
After 5 months of using the Kiierr Laser Cap, my hair is fuller, and I feel years younger. I was skeptical at first, but after speaking with their helpful team, I decided to try it. To my surprise, it really works! Plus, their customer service is fantastic. Highly recommend!
Significant hair growth!
I have been using the Kiierr Hair Restoration Cap for the past 18 months. I have received significant hair growth. Attached are my before and after photos showing the hair growth. I highly recommend the Kiierr Cap.
John J
It’s a game-changer for my hair loss
Easy to use cap which I have been using for about 5 years now, every other day. My hair strands have become thicker & have less shedding. I would definitely recommend the Kiierr cap, especially due to the scientific backup.
Vincent R
Highly recommend all Kiierr products!
The laser cap definitely helped regrow hair over the balding spot on the crown of my head and on my thinning/receding front hairline! I also use the Kiierr shampoo, conditioner and vitamins. I highly recommend all Kiierr products!
Dennis F
Amazing for male pattern baldness!
I highly recommend this product to anyone with hair loss. Male pattern baldness started in my 20s with a receding hairline and thinning crown. I have seen awesome results with red light therapy and it was worth every penny.

Can daily shampoo really support hair growth?
Yes! Kiierr’s Shampoo uses 12+ science backed ingredients to gently cleanse, protect the scalp & help block DHT for stronger, healthier & fuller looking hair with every wash.
How does Kiierr’s shampoo help reduce hair loss?
The shampoo is designed to fight one of the biggest culprits behind thinning hair: DHT buildup on the scalp. DHT can weaken hair follicles over time, but the formulas use science-backed ingredients and botanical extracts to gently block DHT while cleansing, nourishing, and hydrating the scalp. A healthier scalp environment means stronger roots, less shedding, and a better foundation for thicker, fuller-looking hair.
Why is blocking DHT so important for hair growth?
DHT (dihydrotestosterone) is a hormone that can attach to hair follicles and cause them to weaken over time. When DHT levels are reduced, follicles can stay nourished, extend their growth phase, and regrow fuller, healthier hair.
What makes Kiierr’s shampoo different?
Unlike standard shampoos that only clean the surface, this dermatologist developed formula uses over a dozen natural ingredients like Zinc PCA, Green Tea, and the Kapilarine complex to target the root causes of hair loss (DHT buildup and poor circulation) while also cleansing and rebalancing the scalp.
How does a healthy scalp support better hair growth?
A clean, balanced scalp is the foundation for healthy hair. By removing buildup, soothing irritation, and improving blood flow, this shampoo creates an ideal environment for follicles to thrive and grow stronger, thicker strands.
What is the Kapilarine complex, and why is it so effective?
Kapilarine is a natural botanical blend of Kigelia Africana, Ginkgo Biloba, Salvia, and Cinnamon extracts. Together, they boost scalp circulation, calm inflammation, and inhibit the 5-alpha reductase enzyme that leads to DHT production, helping extend the hair growth cycle and improve overall scalp health.

The smell is subtle and fresh. I love how my scalp feels tingly clean without being stripped.
Hannah J.
I pair these with my laser cap, and together it feels like I’m giving my hair every chance to grow stronger and healthier. It feels like a full system instead of just washing my hair.
Sophia K.
The first wash left my scalp feeling so refreshed. After a few weeks, my hair felt stronger and looked shinier. It’s not a miracle, but it’s definitely a noticeable improvement.

My scalp used to flake a lot, and now it barely does. That alone makes this worth it, and on top of that my hair feels stronger too.
Rachel L.
My husband and I both use these now. He struggles with thinning and I just like how soft my hair feels. The spearmint scent in the conditioner is refreshing.

This duo has become part of my routine. I notice less hair in my brush and my ponytail feels a bit thicker than it used to. It’s a small change, but for me it’s noticeable and encouraging.
Michael G.
The shampoo cleans without drying out my ends. My scalp feels refreshed, and the conditioner makes detangling much easier. My hair hasn’t felt this manageable in a while.
Jenna F.
I’m impressed by how soft my hair feels after using these. Even my stylist commented that my hair looks healthier and easier to manage since I started.
Claire T.
The shampoo and conditioner together have really improved how my hair looks day to day. It feels fuller, stronger, and less brittle, which makes styling easier and more fun.

Sam W.
I wasn’t sure if a shampoo could actually help with thinning, but I can honestly say my hair looks and feels healthier since I switched.
Kelly S.
I didn’t expect much, but after three weeks I can see a difference in how my roots feel. My hair doesn’t shed as much in the shower anymore.

For me, the biggest change has been less itchiness. My scalp feels calmer, and I’m not scratching all the time anymore. My hair even looks shinier which I wasn’t expecting.
Kevin H.
I’ve been struggling with thinning hair for a while, and honestly I wasn’t sure anything could help. This shampoo and conditioner leave my scalp healthier and my hair a little fuller each week.
Derek P.
It took a few washes before I noticed a change, but now my hair stays cleaner for longer and doesn’t get as oily at the roots. That alone makes me want to keep using it.
Megan J.
Love that the conditioner makes my hair soft without leaving it greasy or heavy. It feels like the perfect balance.
Matt B.
The conditioner is lightweight but still makes my hair feel moisturized. I don’t get that heavy, greasy feeling like other brands.
Brian D.
It’s only been a few weeks, but my hair feels stronger already. I’m noticing less breakage when I brush, and my ends look healthier.
Danielle R.
This was meant for the whole family, but the biggest surprise was how it helped me. My hair feels lighter, softer, and way less tangled after each wash.
Laura E.
This is the first conditioner I’ve used that doesn’t weigh my fine hair down. It still feels light but leaves my hair soft and easy to brush through.
Anthony C.
My shedding has gone down noticeably since using these. I used to see a lot of hair in the drain and on my pillow, and now it’s maybe half of what it used to be.
