Meh

3 stars out of a maximum of 5

I'm usually loathe to take the time to review a bad experience with a product, but I'm making an exception because there's so much hype around this. It makes my hair feel like straw! and it becomes hard to style. Nope, not for me.

Seems to be working

4 stars out of a maximum of 5

Introduced this to my routine recently and does seem to make a difference. However, I was surprised by the size of the bottle when it arrived. I don't mind paying higher price points for good products, but the size of this for the price was a bit much! I use sparingly, section my shoulder length hair intro three and use one pump on each.

Wish this wasn’t so expensive

4 stars out of a maximum of 5

I think this is really effective and it has helped my hair, but the price is not worth it and that’s why I’ve given it a 4 instead of 5. I can’t justify this for my long and full hair, so I will use other products when this runs out.

Expensive but worth it

This really does help to strengthen the hair! You only need to use it once a fortnight to maintain the hair so although it is expensive it lasts a long time

HG hair product

I have very fine hair and this gives a little weight and volume to my otherwise limp hair. It also prevents breakage. I prefer it to Olaplex which I found drying.

Soft hair

5 stars out of a maximum of 5

Tried this after my hairdresser used some salon treatments on me. After being a shampoo/mask person for years, the idea of not conditioning was weird to me but I thought ‘trust the process’! Few pumps in your hand and rub together so your hands go white, then run through your hair. Wait few mins, no having to jump back in shower to rinse. What was I left with? Soft and silky hair.

I have now bought the full size, I'm glad I started with the trial size. Has made a huge difference to my hair strength.
