Description
The Kiierr Daily Hair Growth Nutraceutical isn't just another hair vitamin, it's a clinically-supported, DHT-blocking formula engineered to attack hair loss at its hormonal source.
While most supplements offer a one dimensional fix, Kiierr's advanced blend of 15+ all-natural ingredients works from the inside out to slow shedding, strengthen existing strands, and create the ideal internal environment for real, visible regrowth.
Whether you're dealing with pattern hair loss, hormonal thinning, postpartum shedding, or age-related hair changes, this formula was built for you. And when paired with the Kiierr Laser Cap, you're not just treating hair loss, you're attacking it from every angle possible.
Ingredients
Every ingredient in the Kiierr Daily Hair Growth Nutraceutical was chosen for a specific reason.
Here's what's inside and why it matters:
Saw Palmetto (300 mg) — The most clinically studied natural DHT blocker available. Inhibits the enzyme that converts testosterone into DHT, the hormone responsible for follicle shrinkage and hair thinning.
Nettle Root Extract (100 mg) — Competes with DHT at receptor sites to prevent follicle damage, while delivering key minerals like zinc, iron, and silica directly to the scalp.
Zinc (10 mg) — Directly linked to hair follicle health. Helps suppress DHT production while supporting the protein synthesis your hair needs to grow stronger.
Horsetail Extract (100 mg) — One of nature's richest silica sources. Strengthens hair structure from within, reduces shedding, and improves overall strand resilience.
Biotin, B-6, Folic Acid & Pantothenic Acid — Essential B vitamins that fuel keratin production, support healthy cell turnover, and ensure your follicles are getting the nutrients they need to thrive.
Other Ingredients: Gelatin (bovine), vegetable magnesium stearate. Contains Soy & Shellfish. GMO free. Paraben & petroleum free. Formulated in the USA.
Instructions
Take 2 capsules daily — one with your morning meal and one with your evening meal. That's it.
For best results, use alongside the Kiierr Laser Cap as part of your daily hair growth routine. The laser cap stimulates your follicles externally while the Nutraceuticals protect and nourish them internally. Acomplete, two-pronged approach to fighting hair loss.
When will I see results?
Hair growth takes time. Most customers begin noticing changes between months 90 days with the most significant results reported at the 6-month mark. Consistency is everything. We recommend committing to a full 6-month regimen for optimal results.
Consult your physician before use if you are pregnant, nursing, or taking prescription medications.

I started the Kiierr Daily Nutraceuticals skeptical, but by month 3 my part looked noticeably fuller. Month 6 I paired it with the cap and the difference was undeniable.

I've been on the vitamins for 7 months. My barber actually asked what I'd changed. Combined with the laser cap, my crown has filled in more than I thought possible.

After menopause my hair thinned dramatically. The Kiierr Nutraceuticals gave me my thickness back. I wish I'd found these two years ago.

I use the vitamins and the cap together every day. At 47 I was losing hope. Six months in and my hairline has genuinely come back and my confidence is through the roof.

How do the vitamins actually work
The Kiierr Daily Hair Growth Nutraceuticals target hair loss at its hormonal root. Ingredients like Saw Palmetto, Nettle Root Extract, and Zinc work together to inhibit 5-alpha reductase — the enzyme responsible for converting testosterone into DHT, the primary hormone that shrinks hair follicles and causes thinning. By reducing DHT activity at the follicle level, the Nutraceuticals help slow hair loss and create a healthier environment for new growth — from the inside out.
Why should I use them alongside the Kiierr Laser Cap?
The two treatments work on completely different mechanisms, which is exactly why they're so powerful together. The Kiierr Laser Cap uses FDA-cleared low-level laser therapy (LLLT) to energize hair follicle cells and stimulate regrowth at the scalp level. The Kiierr Daily Hair Growth Nutraceuticals address the hormonal cause of hair loss internally. Think of it this way: the laser wakes your follicles up, while the Nutraceuticals make sure DHT isn't shutting them back down.
How long does it take to see results?
Most customers using the Kiierr Daily Hair Growth Nutraceuticals alone begin noticing changes around the 3–6 month mark — consistent with how long the natural hair growth cycle takes to reflect internal changes. Customers who pair the Nutraceuticals with the Kiierr Laser Cap often report seeing results sooner, as the laser therapy accelerates follicle activity while the Nutraceuticals work to sustain and protect that growth long-term.
Are they safe?
Yes. Both the Kiierr Daily Hair Growth Nutraceuticals and the Kiierr Laser Cap are drug-free, non-invasive, and designed for daily use. The Nutraceuticals contain all-natural ingredients with no known interactions with laser therapy. The recommended dose is 2 capsules per day — one with your morning meal and one with your evening meal — making it easy to build into your daily routine alongside your laser cap sessions.
What makes them different from a basic hair vitamin?
Most hair vitamins stop at Biotin. The Kiierr Daily Hair Growth Nutraceutical formula goes further by combining DHT-blocking botanicals like Saw Palmetto (300 mg) and Nettle Root Extract with follicle-supporting nutrients like Zinc, Biotin, Vitamin B-6, Folic Acid, and Horsetail Extract. Each ingredient plays a specific role — whether it's blocking DHT, strengthening hair structure, or nourishing the scalp — making this a comprehensive internal treatment rather than a generic supplement. When paired with the Kiierr Laser Cap's external stimulation, you're addressing hair loss from every angle.

Dana M.
I started taking the Kiierr Daily Hair Growth Nutraceuticals about 6 months ago after noticing my part getting wider. I wasn't expecting much honestly, but by month 4 my hair felt noticeably thicker. My hairdresser commented before I even said anything. Really impressed with these.
Yvonne K.
Post-partum hair loss hit me really hard after my second baby. I was embarrassed to even wear my hair down. The Kiierr Nutraceuticals helped slow the shedding within the first couple of months and by month 5 I had real regrowth along my temples. Feel like myself again.
Theresa B.
I was skeptical about supplements in general but the ingredient list on the Kiierr Nutraceuticals is unlike anything else out there. Five months in and my hair is shedding far less and growing noticeably faster. My stylist actually asked if I'd changed something. I had.
Raymond G.
I've tried every hair vitamin on the market. Most are just biotin with fancy packaging. The Kiierr formula is different. You can tell by the ingredient list alone. Six months in and I have less shedding and noticeably more density on my crown. Worth every penny.
Gloria R.
I lost a significant amount of hair going through menopause and had basically accepted it. A friend recommended the Kiierr Nutraceuticals and I figured I'd try them. Six months later I have actual baby hairs growing in along my part. I am so glad I didn't give up.
Angela S.
I was losing hair after stopping birth control and was desperate for something natural. I've been on the Kiierr Nutraceuticals for 5 months now and the shedding has slowed dramatically. My ponytail is visibly thicker. So relieved I found something that actually works.
Susan L.
I've been taking the Kiierr Daily Nutraceuticals for about 9 months now. Slow and steady is the name of the game with these. Around month 4 things started clicking and now my hair is the fullest it's been in years. My dermatologist was genuinely impressed at my last visit.
Christine V.
I use the nutraceuticals daily and pair them with the laser cap four times a week. It took patience but around month 5 everything changed. My hair is thicker, my scalp is healthier, and I finally stopped dreading washing my hair. Kiierr has genuinely been a game changer for me.
Carolyn H.
I'm 61 and started the Kiierr Daily Nutraceuticals after my doctor mentioned my thinning was hormonal. Four months in and I'm seeing small hairs along my hairline that weren't there before. At my age I honestly didn't think regrowth was possible. Pleasantly shocked.
Nate C.
Easy to add to my morning and evening routine. One capsule with each meal. I've been consistent for 7 months and the results speak for themselves. Less shedding, thicker strands, and my wife says my hair looks better than it did 10 years ago.
Trevor B.
I've been using the nutraceuticals alongside the laser cap since January. The combination is no joke. My hairline has filled in more in 6 months than it had in the previous 3 years of trying other products. Wish I had found Kiierr sooner.
Brian W.
I started with just the laser cap but added the nutraceuticals after reading about how they complement each other. That was the turning point for me. Within a few months of using both together I started seeing growth I hadn't expected. The science behind the combination makes total sense.
Harold F.
I'm 70 years old and my doctor suggested I look into natural DHT blockers before considering anything prescription. Found Kiierr and haven't looked back. Eight months on the nutraceuticals and my crown has more coverage than it's had in years. Remarkable for my age.
Melissa T.
I use the nutraceuticals with the laser cap three times a week. Started both at the same time about 8 months ago. The before and after photos I took are honestly hard to believe. My confidence is completely back. I tell every friend who mentions hair loss about Kiierr.
Jason M.
I've been using the laser cap for two years and added the nutraceuticals six months ago. Adding the vitamins was the best decision I made. The cap maintained what I had but combining it with the nutraceuticals actually pushed new growth I wasn't seeing before. Great products.
Olivia N.
I started the Kiierr Daily Hair Growth Nutraceuticals after years of watching my hair thin along the crown. I paired them with the laser cap from day one and committed to being consistent. By month 3 the shedding had slowed and by month 6 my hair was fuller than it had been in a long time.
