USA Dekohair Hair Serum for Thinning Hair and Root Volume, 2 fl oz | Lightweight scalp serum, supports fuller-looking hair, adds root volume, promotes the appearance of density, daily use

Omg you need to try it. Yes it’s expensive, but I see a difference. New baby hair. My saver. Big difference. I’m using it every night. Highly recommend

I wish someone would tell me how awful it smells. First night and I can't fall asleep, it smells so bad. Cannot imagine using it daily

It’s the best ser I’ve ever tried. It worths its price 100%. I tried for my street hair loss serums with aminexil and it doesn’t help and after my hairdresser advised me this one. It helped me so hard, but I decided to save some money and after to maintain my result I bought weleda with rosemary. It’s definitely worse and weaker than decohair. So I highly recommend this!!

I’ve been using this hair serum for a few weeks now and I’m honestly impressed. It leaves my hair feeling incredibly soft, smooth, and manageable without making it greasy or heavy. The frizz control is excellent, even on humid days, and I’ve noticed a real improvement in shine and texture. A little goes a long way—just a few drops are enough to make a big difference. Plus, it smells amazing! I’ve received several compliments on how healthy my hair looks since I started using it. Definitely a new staple in my haircare routine. Highly recommend!

Thanks to this serum, my hair loss has finally stopped. I continued my 3-month course. I even bought a mini microscope to track the progress. Guess what? My whole head is covered with baby hair...finally we have moved forward...before buying it, I looked through a lot of reviews (it is very popular and well-known in Europe) and also turned to AI. I can say that this is the only thing that helped me in the fight against hair loss and this product will always be in my routine care from now on.

I bought this product after I saw a big result on my friend. So hopefully it will work on me too :) I just started to use it, I will come back to my review in 3 months from now.

I used it only once. It gave me nausea and a headache. Later, I found out it contains Butylphenyl methylpropional (Lilial) — a toxic ingredient banned in the EU for being potentially carcinogenic and harmful to reproduction. Don’t buy this product if you value your health. Amazon refused to refund me. I feel scammed and want to warn others. Please check ingredients before using anything on your skin or scalp

I am very satisfied with this product. After 3 months of using it I noticed the significant growth of hair. The product also does not make my hair to look dirty, there is no need to wash hair after it. I recommend to buy it. I have already bought my second bottle as a gift to my sister.

Best product from what I tried so far

I've been using this product for a few months to check whether it works at all. To do so, I've only applied it to the right side of my parting. What I can say is... I don't see any difference, so for me, it just doesn't work. Waste of money P.S. I was diagnosed with androgenetic alopecia.

I recently purchased a Deco3 Hair lotion, expecting the same high-quality product I’ve used before from the official website. However, I was extremely disappointed to find that this product is clearly not authentic. The composition is completely different—the genuine lotion has a light, watery consistency and a pleasant scent, while this fake version smells off and has an oily, almost grease-like consistency. I’m absolutely shocked at how blatantly this product has been counterfeited—it bears no resemblance to the original in any way. Be cautious when purchasing, as this fake version is a complete letdown and a waste of money.
