Trust the Process.
After 6 months of using the shampoo and conditioner I can honestly see a thicker head of hair and my thinning sides feel and look thicker. I owe my thinning hair to menopause symptoms so if you are going through same - Id recommend. But be patient, You have to trust the process as it does'nt happen overnight. I am 6 months in but saw a difference after 2 months using twice weekly. Only downside I found the serum to be a bit heavy for me but the Shampoo and conditioner are fab.

It works
I wanted to wait until I had finished the bottles before I put my review. I seen lots of negative reviews but I gave it a chance. Firstly it is the best shampoo for getting your hair squeaky clean and the menthol smell is so lovely, my head feels so fresh after each wash and it litera tingles. I did not notice any more hair shedding than I would normally get with each wash. I didn't see any difference for some time but I trusted the process. I had a small balding patch up the front of my head which I could not explain how it happened. After 5 weeks of washing my hair 3 times a week with this treatment I couldn't believe that I started seeing tiny hair growth coming from my bald area. I did combine taking Biotin with the treatment which I feel also boosted it but honestly I am so happy and I will continue to use this product as I can see the difference.

Works well when used consistently
I’ve used this product twice during periods when my hair shedding increased, and both times I noticed a clear difference. When used regularly, my hair fall reduced significantly. It doesn’t work overnight, but with consistent use it really helps strengthen the hair and improve scalp condition. I personally saw results, which is why I keep repurchasing it. I would definitely recommend it to anyone experiencing hair thinning or increased shedding, as long as they are willing to use it consistently.

Bad Packaging
Product is good but when put out for delivery needs to be wrapped up and not just stuck in an envelope where it had burst open and some of the product had leaked out into the envelope. This conditioner is expensive enough without it being wasted because of bad packaging.

Hair treatment
Shampoo and conditioner excellent. Mouse thickens hair but can leave it sticky spray with leave in conditioner or coconut wax spray and it won't be sticky

It works!
This stuff works- it may take a bit of time but has transformed my menopausal, long covid and over processed hair back to thick and healthy. I won’t be without it now and have been using it for over a year. The bottles I’ve bought on Amazon are usually a year from the production date but apparently as long as they aren’t opened, the product will last up to 3 years and for a year once it’s opened. It’s significantly cheaper buying older bottles from Amazon and I buy 1litre bottles and decant into smaller ones.
