Actually helped reduce hair loss, increased hair growth, and thickens your hair!
I have used several products over the years for my fine thin hair. In my early thirties I began to experience significant hair loss that took years to recover from. I have been using the Boldify product line for about six months now and have seen significant hair growth, a major reduction in hair loss during brushing and washing, and I immediately saw the difference in body, shine and softness when styling. The scent of the product is nice, where some hair growth products either have no scent or are not pleasant at all. The product is also concentrated so a little goes a long way. I am still using my first bottles that I bought in July. I do mix the shampoo and conditioner with my regular body building shampoo and conditioner as well, since this product is a bit pricey it helps to stretch the use. The serum has worked wonders on the health of my hair and has helped in growing out a very short pixie cut quickly. My hair is softer, shinier and stronger. I highly recommend this product and will continue to use it as it has done wonders and has not let me down!

Amazing really- and I was skeptical at first.
Ok- so I have bought other products in this line, and really liked them for the most part overall. They are great at imparting volume. But this stuff really is incredible- I think it is the best one of all their products. It not only imparts volume, but it makes the hair shaft smoother, and I would believe that with prolonged use it will decrease breakage. It also smells really good. I now use this stuff every morning. I have curly hair, so I put a dab on my hands, and run it from scalp/roots to ends. It restores curl, decreases frizziness (possibly by coating the hair shaft?), and adds volume...and smells great. This is now an everyday product, and it appears to be the only product that I need. I am going to order more as soon as I start to run low. This may be the only product that you need. I will admit that I was skeptical at first. There are a lot of these serum products on the market. But after using this I cannot imaging NOT using it. I will be curious to see if it make a significant difference in the long run with increasing growth and decreasing breakage. But it has been so good for me that even if it didn't, I would still buy it for the immediate effects, and improved overall hair condition and appearance. Great product.

Makes my hair feel great!
This is a really good product. Smells great but not overpowering. It makes your hair feel silky smooth and does give you that blow out look. I have only been using the product for about a month and I haven't seen a big difference in he volume of my hair but maybe that come with more use over time. But I would say even though I purchased for volume and I didn't see big differences, I love the product. It come in a bottle so it's easy to travel with. I like that much better than a pump or aerosol. It is a bit on the expensive side but you only need a small amount so I believe it will last a long time. Overall I really like the product and am hopeful that over time it will increase volume/health/thickness of my hair as advertised.

Not a bad product, just not exactly what I’m looking for.
The smell is a bit strong for me, but I got used to it after a while. The consistency is almost slimy so it spreads... and spreads and spreads. It’s easy to go overboard when squeezing the product out of the bottle and too much really weighs my hair down and makes it look stringy (I have normal thickness wavy hair). I can’t say I’ve noticed any hair growth while using this product, but I also chose not to use the shampoo/conditioner that match it (because I’m so in love with another shampoo/conditioner at the moment). I was hoping this product would enhance my waves a bit and help tame my frizz, which it’s doing an okay job at. All in all it’s not a bad product- I was just hoping for a little more. It does have heat protection though which I like since I straighten my bangs everyday.

I cannot be happier with this product!!
This product SAVED my hair!! I can’t express enough how pleased I am and thankful to the ones before me who wrote reviews. I read a lot of reviews before purchasing a product and I think this is my all time favorite purchase all year! From the first time I used this I lost only a tenth of how much hair I was losing. I thought it was normal to lose a lot of hair when combing your hair because it’s dyed & highlighted... I was completely wrong and feign feigning ignorance because I didn’t want to believe I was losing a ton of hair though my mom was truly concerned. This product not only saved my hair, smells nice, and not greasy feeling before & after use. My hair has been soft, already can tell my hair has started to have new growth too where it was breaking! I’m just upset no one told me before I needed a product like this for my hair. I really can’t wait to dye and highlight my hair again because I know NOW I won’t lose a lot and my hair can remain healthy with this product. For anyone reading and concerned if the product is only good for certain hair types, I can attest as a mixed ethnicity it will work on all types of hair!!

Really good volume
I have a lot of really fine, straight hair, and lately, I've been shedding like crazy. After using this product for about six days, I'm shedding less. But the volumizing effects are what really surprised me. A small amount goes a long way, and the amount of volume you get is incredible. It's also left my hair smoother. It's easier to detangle. I do use it daily. Some people say that if you apply it on dry hair, it's very tacky or sticky, so I just wet my hands and run my fingers through my hair before application. I haven't experienced any stickiness so far. The scent is also very clean and not overpowering. Edit: I've used this daily now for over a month (about 5-6 weeks). My shedding has all but stopped. My hair is thicker, smoother, and often looks like I've done a quick blow dry even when I haven't. I will definitely be buying this again.

Best product for thin, fine hair I have used!
I am so excited about this product! Getting older has enough trials without having to deal with thinning hair and being self conscious about it. I have always had fine hair but the last couple years I have noticed that I am really thinning on top to the point it affects my self image. My Dr. said it was due to my medications, hypothyroidism and simply age. Heredity also is to blame. I have honestly tried every product that promised results but was always disappointed and poorer! I gave this a try after reading the reviews but didn't expect much. Was I wrong! This serum is awesome and lives up to its rep. I am amazed at the change with 1st use. I work just a dime size amount through my towel dried shoulder-length hair concentrating on the top problem area and usually just blow dry. Hair has volume and shine and the difference is very apparent. Doesn't weigh hair down, not sticky or stiff - I am so happy to have found this product line. I use this with their thickening spray (which I am even more impressed with) and I have my confidence back! I haven't tried the shampoo yet but can't wait to try it. I did purchase their hair fiber product per it's reviews but haven't used it yet as it looks like it may have a learning curve to its use. Can't believe I have spent my time on a long review but am so excited about this. Just try it, you won't be disappointed!

Do you have FINE Hair? What this product REALLY does.....
Calling this a "Regrowth Serum" is just a tad deceiving. In my humble opinion, what this product TRULY does is strengthen the "existing" hair you have on your head, so there is less breakage when you wash, comb, style and/or brush your hair. As a result..... if LESS hair is breaking during these daily activities [then naturally- over time] your hair will become thicker as new growth occurs and 'older' hair stays on your head. Where it belongs! For anyone with fine textured (easily broken) hair like me, I think you'll be pleased. After only 3 applications, I noticed LESS hair laying in the shower drain after washing/conditioning : ) And when combing out my long, wet hair--- instead of removing huge globs of broken hair from the comb, I happily saw an improvement! This serum seals in moisture and protects without stickiness, it did NOT weigh my fine hair down and also gave it a beautiful shine upon air drying. Oh and if you have color treated hair, there's no need to worry. The condition of my hair feels better than it ever has before. Took one star off because hair didn't feel thicker in One Day. Perhaps it will in a month as breakage decreases :crosses fingers: Hope this review was helpful.

Great for conditioning and controlling without the need for other products
I have short, thinning hair, balding at the crown. Recently, I left the top to grow out a bit and it was quite difficult to style and control. I decided to try this product for the thickening properties but I found it keeps my hair under control and in great condition without me having to add other hair products. It possibly adds a bit of volume, but I don't have enough hair for that to be noticeable.

Overpriced and doesn’t work
Heard great reviews about this serum and having bought the shampoo and a few other boldify products I hoped for great things. Please also be aware; The seller is not the official BOLDIFY seller so usually when you get items from the official boldify Amazon seller there is a voucher inside so you can claim a free same product again, which I’ve done on a few other boldify products which is a great offer so I thought with this being so expensive at £40 I would be able to claim the free bottle as usual making it really £40 for two but no you can’t claim this with this seller. As for the product itself it does absolutely nothing for my hair, it’s as limp without body as before. The boldify shampoo helps but don’t waste your money on the serum so crazily expensive too!! Buy a £3 mousse it will work better!
