My hairdresser is impressed!
I really like this product, I have had two of the smaller packs and now bought these big packs with birthday money. It’s not cheap, but I find that I don’t need to use a lot. I only put a couple of squirts in my hand and only put onto the scalp, I use my usual shampoo/conditioner on the lengths, you can feel your scalp tingle. After months of using it my hairdresser says my hair feels better than she has ever known it, and she has been doing my hair for over 30 years!

Bottle split in transit
I love this product therefore brought the biggest size 1000ml, unfortunately the item was damaged the shampoo bottle had split emptying part of its contents. There is no option for reporting this without arranging a return, I don't want to post a split bottle back. Love the product but may consider buying from somewhere else in future.

Good for thinning hair
I use this product because my hairdresser recommended it. Pleased it’s available on Amazon because the salon doesn’t always have it.As I wash my hair every day, these large bottles are good for me. I keep smaller bottles in the shower to decant into from the large bottles.As for the products themselves, my hair feels thicker and healthier. I have tiny bald spots which are better hidden than before.

Great Value!
I've been using this product for years and so too has my husband. I alternate with Oliplex and find it perfect for holding cut and colour.

Arrived promptly and on time
This product was to restore hair loss but this will take time to see if it works.
