Kintsugi Hair Review: A Detailed Look

Reviewopedia staff  -  Updated:  November 12, 2023


Kintsugi Hair markets a line of hair supplements intended to provide women with scientifically-supported formulas that strengthen and beautify hair.

About Kintsugi Hair

Paul Lindsey, the creator of Kintsugi Hair supplements is a self-described hair science expert and the owner of No. 275, a top-rated salon in the heart of Beverly Hills.

In working with clients in Los Angeles, including celebrity clients, Lindsey realized that there was a real need for an active serum that would help support hair growth and improve hair health, strength and density.

Lindsey worked with Dr. Layke and Dr. Danielpour, two cosmetic surgeons in Los Angeles, to learn more about the developing science in cosmetic medicine, including the latest studies around improving hair health.

Products & Ingredients

Kintsugi Amplifying Glaze

One of the company’s most popular products is a volumizing serum treatment powered by marine extracts, premium polymers, and restorative protein compounds.

The key active ingredients include proprietary blends developed by leading cosmetics laboratories:


SymHair Force 1631

Developed by Symrise, this formula combines Pentylene Glycol (and) Isochrysis Galbana Extract.  

This is a natural extract from a South Pacific Algae that has  anti-hair loss and hair revitalizing properties.

According to the company, in their trials, SymHair Force 1631 showed an increase in anagen hair of 10.5% and telogen hair of 11.7% against a placebo.  It also showed an increase of hair and density in beard hair.

Overall they state that this ingredient reduces thinning of hair, prolongs the growth phase and delays the entry into the regression phase.  It also has hair strengthening properties that prevent hair breakage.

Similar ingredients are found in Keranique - Lift & Repair Treatment Spray.



A trademarked plant derived formula that fights hair loss via a two pronged approach targeting poor scalp micro-circulation and follicle atrophy.

First, it works to keep your hair follicles healthy to avoid brittle hair that can break.  Next it increases cell metabolism to slow down hair loss.

The product data sheet shows results of a clinical study in which 67% of participants had their Anagen hair (new growth) number increase vs a placebo.

It is oftentimes used in conjunction with or as an alternative to the prescription hair loss medication Minoxidil.

The ingredients are: Biotinyl-GHK (a form of hair vitamin biotin), Apigenin (a flavonoid found in citrus plants, and Oleanolic acid (derived from olive trees).


Kerastore 2.0

The manufacturer claims that this compound can mimic the natural proteins found in your hair. Using the latest technology it can offer targeted repair to damaged hair surfaces.

In other applications it was shown to improve the properties of wet hair, making it easier to remove tangles and ease wet combing.

The remaining ingredients listed on their website are common bases of most hair serums, shampoos, and conditioners.

Overall, the product is focused on restoring hair health and improving density and thickness while preventing future damage from occurring.  

Using proprietary ingredients, this supplement aims to support a longer growing cycle for the hair on your head.


Additional Kintsugi Hair Products include:

  • Awakening Mist - Scalp Tonic
  • Infused Hydration - Cleansing Conditioner
  • Moisture Bond - Conditioning Spray
  • KeraNew - Nourishing Hair Complex (Full Review)

It appears Kintsugi Hair uses a similar formula for all their products.  

They attempt to form a unique blend using a base of 3 key proprietary scientifically formulated compounds on top of standard hair care ingredients.

You came into this world bald and most will leave bald
June 9, 2023

I have been using these bills and the bald spot still shins and brightly as TIMES SQUARE on New Years Eve.

It might work for others..............but I would suggest you just save your money and deal with the fact that you are losing your hair.

I know it's a tough pill to swallow and accept. But Heck we came into the world bald for the most part, and we'll leave this earth with that darn bald spot

I have been using the amplifying glaze for 3 days and absolutely love it. In just 3 days I have less tiny pieces of hair from breakage all over my sink.

I’m getting my hair done now and my stylist commented on how great my hair feels. Can’t wait to see how much better it gets with time. Smells great too n

It works...I kid you not
January 11, 2023

After going thru Alopecia for 2 years at which time I had to shave my head 2x because it kept growing back in spots only..... I decided to try hair growth pills....I tried them ALL...everyone of them. THEN I came across Kintsugi and it changed my hair into this flowing, thick growing hair. I am aamzed and have cried tears of joy. I have been faithfully using this for 6 months. It is part of my daily supplements that I take. I will never stop.

IF you have tried them all........its time you gave Kintsugi a try.

peace & love to all

You Get What You Pay For!
December 4, 2022

In the past I've tried many hair growth systems with no success UNTIL I tried Kintsugi! With very baby fine hair every strand counts so when it falls out you really notice. After using Kintsugi's Keranew capsules for 1 month I noticed a big difference with less hair in the sink or even on my pillowcase. After 3 months I too noticed that not only was my hair growing back but it grew back in my original color! And more than that my eye lashes were growing longer and thicker!

Being that it is somewhat pricey I, unfortunately, decided to switch to a different manufacturer that was less expensive. Within 1 month I noticed my hair was falling out, again, as well as my eyelashes becoming thin and short. What a big mistake. I'm now back to using Kintsugi Keranew and will stay as a very very satisfied customer. The old adage, at least for me, 'You Get What You Pay For' still applies.

Thank you, Kintsugi!

Side effects
September 18, 2022
Just a question: what are the potential side effects to be aware of? I tried a different product and high blood pressure was a potential. It did cause that for me. So I stopped and my BP returned to a healthy level.

Dee October 12, 2023

My keyboard is a bit broken

aside from that I do know what you are talking about

I too purchased a liquid solution from a website that promised helping to thicken/regrow your hairline

But before I used the product, and there was a review submitted revealing that her blood pressure shot up and she

ended up going to the hospital as she was convinced that the

hair growth product was the cause So with that I threw away

the bottle and chose to not take a chance I did not lose any

amount of money that was of any consequence

So read reviews first because solutions can be absorbed through the skin and possible affect your health

Truly, I was disappointed, but my high blood pressure has not been put at risk

I stay on my meds and search for other products

New hair growth.
August 9, 2022
I have always had fine hair, it has become thinner as I have aged, especially in the crown..after Covid in June, more hair fell out. I have now been taking Kintsugi for about 6 weeks, and already can see new hair growth in all areas. Also, the new hair growth is dark brown, my original color instead the gray that I have been seeing for the last 7 years! Not only am I growing new hair, it is growing in my original color!

CorenHurtt October 09, 2022

Pro stylist. Covid hair loss is common around 4 months after covid. You are forced into the fall out phase of hair growth. As fast as the hair falls out is as fast as it grows back and it could come in in a different color and texture. So it doesn't mean this supplement works. Your hair growing back in is supposed to happen.

Side effects
July 20, 2022

I’m writing this review only because I couldn’t find anyone else with the side effects the pills gave me. After 5 bottles my hair looks much better, thicker, even my eyelashes look fuller and longer. But I get this rash all over my body, really itchy and I had to stop the treatment, the product is great it works, but I guess for some people like myself it's better not to take it! What a shame.

AmberSmith July 26, 2022

hair has more body & hold
May 25, 2022

after taking 2 capsules daily for almost 3 months, I do believe my thin, weak, colored & permed hair has new vigor & bounce!

My hair seems thicker with new growth in bare areas & it seems stringer, holding curls & needing less attention to maintain --- I want to order more & look forward to continued improvements!

Repair and restore
May 22, 2022

The Kintsugi hair supplement has hugely helped my fine hair to grow back after being damaged from bleaching it finally.

I have been using the supplements for two months now and I’m very excited to see how continued use will improve my hair growth and restoration from the bleaching damage!

My Hair stopped falling out!
May 20, 2022

I always had beautiful, thick hair, but in December I contracted a bad case of Covid 19. Since that time, my hair has been dry and falling out at an usually high rate. I was actually afraid I was going bald!

I tried the Kintsugi supplements...and after a month, I was pleased to see that my hair stopped falling out. I've been using the supplements for 2 months now, and my hair is definitely looking much better. I would definitely recommend this product!

Big change
May 19, 2022
So far the results with the pills have been great. Softer fuller it doesn't seem to be falling anymore. My hair has definitely changed. It is more manageable and holds my natural wave for days. I like life to be simple and to not have to use a lot of products so this product really works for me.

This really works for my hair!
May 17, 2022
My hair hasn't felt this good in years! It works so well, my hair has more life to it and looks great! I love it!

Hair Growth Apparent
May 15, 2022
My hair had receded at the crown, top and sides. In less than 2 months I have new hair growth. I noticed fine hair growing in after 30 days. Within 60 days it was noticeable by others. The only thing lacking is auto subscription.

It works as advertised.
May 15, 2022

The Kintsugi Hair capsules are excellent. My hair and nails have improved 100% in a short amount of time. I have hypothyroidism which causes problems with hair and nail growth among other issues. My hair use to be thick and long. Now my hair is thin and falling out by the hand full.

After taking this product for over 2 months my hair is stronger, not falling out and growing again. It looks and feels so heathy. My nails were breaking, splitting from the tip to the cuticle, ridges, and so brittle. No more since I started taking this excellent product. I am so pleased. As an RN I recommend this product.

The pills are very potent.
May 15, 2022
Hello. Just wanted to inform you that I am very satisfied so far. My hair has changed alot. I am on my second bottle. My results so far have been awesome. My hair does not fall out like before. It is looking and feeling healthier. I'm starting to fill in where I was going bald. Thanks for this product.

No more thinning hair
May 7, 2022

I've had thinning hair for awhile now and needed to find something that would help grow and make my hair thicker and stronger.

After using Kintsugi for a few months I started to notice less hair falling out on my hairbrush. My hair is now twice as thick and is growing much faster.

Even my hairdresser has noticed the difference.

Love This Product - Really Works!!!
May 7, 2022
I've been taking Kintsugi for over a month now. I have thin hair--but a lot of it (it's mid back length). I'm seeing less and less strands in my brush and comb + my hair looks thicker. My husband even told me (without prompting him - wow) "that stuff you take every morning for your hair is really working-your hair looks awesome." Now, that's a BIG compliment from my lovebug of 20 years who suffered a ruptured brain aneurysm and stroke 17 years ago - he is only 58 now but his short term and long term memory are very limited; he is completely right-sided periphery blind; and, suffers from word confusion. HE ACTUALLY NOTICED!!!

Results from using KeraNew
May 4, 2022
I am so overwhelmed by the results I have gotten from KerNew. I was basically going bald you could see the top of my head from every angle that you looked and now I have a very thick head of hair. I did not take pictures prior to starting using KeraNew but I did take pictures of the results I hope that other people are as thrilled with the product as I am.

KeraNew---Awesome results so far!
May 2, 2022
I am in my mid-60s and have been taking Kintsugi's KeraNew for almost 2 months, with amazing results! I have long hair that had been seriously thinning on top and front sides for a few years, plus shedding a lot in the shower. Since starting KeraNew, my hair has felt thicker and more full, and I have even noticed some new hair growth. Overall, my hair just looks so much healthier. My nails have also responded, becoming stronger and less prone to ridges and splitting. I don't know if it would work this way for everyone, but I definitely recommend giving KeraNew a try!

The Powerful, Effective Duo!
April 29, 2022

My name is Naomi and I am a 45 year old contract Emergency Department BSN Registered Nurse (travel nurse). In January of 2021 I was working a covid contract in a very remote area of Northern Maine near the Canadian border.

During this assignment I started to notice my hair, skin, and nails deteriorating at a very rapid rate, even though I took vitamin/mineral supplements and remained well hydrated consistently. I immediately starting investigating potential causes for these issues. I started using Shapiro MD hair care products at that time.

Although Shapiro hair products did help with my integumentary system issues, it wasn't giving me the level of results I wanted.

The addition of KeraNew with my Shapiro products changed all that. Today, my skin, hair, and nails are thriving. The combination of these two amazing products has been effective above expectation. I will continue to use both products for as long as they are available.
