I'm almost done my third bottle of this serum and I can say it's made a big difference to my hair. I suffered post-partum hair loss and 4 years later it never improved despite good diet and hormonal checks all being ok. I read a few reviews of this serum and was impressed and couldn't wait to begin. It is a thick, clear gel with a distinctly alcohol scent. You apply 4 pipettes to your scalp every night. I found it easier to dispense the liquid into a small saucer then massage it onto my scalp. After 2-3 weeks I started to notice many new, fine, colourless hairs and in a few more weeks they thickened and begin to take on my natural hair colour. There were so many that I had to by the Loreal Root Retouch spray to blend them into my natural hair colour while I waited ...Ā MoreI'm almost done my third bottle of this serum and I can say it's made a big difference to my hair.

There were so many that I had to by the Loreal Root Retouch spray to blend them into my natural hair colour while I waited for enough growth to dye. Can't believe how many new hairs I have, and they are still coming, they are in 3 distinct growth stages now that the third bottle is approximately half-way done. Overall I highly recommend this serum, the new growth is amazing and I won't stop using it until my hair is back to what it was before my pregnancies.

I purchased this L'Oréal professional denser hair serum for my sister who has long fine hair as a gift. The price is a little steep(she would not normally spend this much on a hair product, so it makes a perfect gift). She often complains how hard it is to manage fine hair, I was blessed with thick hair so I felt for her. She loves this product, I was very popular. It's easy to use, the handy screw top and dropper in the bottle dispenses drops of the product to be massaged in. For best results use this every day, 2to 3 drops is all you need and it lasts really well. Infused with serioxyl which is cleverly derived from stem cell technology it works to stimulate hair growth, thickening hair and promoting growth for denser hair. This is massaged into the scalp and left ... MoreI purchased this L'Oréal professional denser hair serum for my sister who has long fine hair as a gift.

This is one of the several new products L’ORƉAL Professionnel just launched and it’s so innovative! I’ve never tried anything quite like this product. I love that you can use it at night time, it’s super easy to use. I just put it on before bed after showering and it’s just that simple. I think it’s so unique that it’s specifically for night time, how clever! I usually wash my hair at night so it’s a great product for me. I personally struggle with breakage so I’m always looking for products to try that can improve that. I’ve definitely noticed an improvement in my breakage since I started using this.

Effective product.
23 April 2023

This stuff works by keeping your follicles in the anagen phase (growth phase). I love the smell of it. My only dislike is the price. It's so expensive! You can get an entire box of liquid minoxidil for less than one bottle of this stuff. But I buy this anyway cause I like to change it up from time to time.

Effective, high quality, but expensive
25 July 2023

Works for me very well. Helps to regrow hair in male pattern baldness. Expensive compared to other products, but definitely worth it. Also, compared with other stuff that stink bad or give you skin irritation, this one has a very pleasant smell and does not irritate skin.I wish they had a discount if you buy a 2 or 3 pack.
