Rescue in a bottle!!
I've given these products a full 2 months before I reviewed. Bottom line is they work. Before: my hair was coloured and long, started thinning after diet and surgery.( I'm an older lady) really dry and thin, tried everything all my usual conditioners nothing worked, I was wearing it up all the time as I could do nothing with it. After: first shampoo, condition and scalp treatment. Hair immediately felt soft and fed.. I only wash my hair twice a week but now it is longer thicker and in good condition, I can use straighteners again. No shedding and my hair is growing back around my hairline. Excellent products. Persevere to see good results 5 stars

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.

Not for me
Unfortunately I ended up losing quite a lot of my hair due to shedding. It also left a residue on my hair, and as a woman it felt crispy when it dried. Not something I'd put myself through again, I'd rather wear a wig.

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.

This hasn't really worked for me. My hair is still falling out after 3+ months of use.
