Colour was perfect. Vibrant & beautiful
been using it for a while and it really works
Wish it was a bigger bottle
Easy too use, may need extra gloves as they break easily. Apart from that it does the job.
Love the colour, beautiful and vibrant. Didnt need much still have heaps left to use.
Awesome range of products! I have been able to trial so many at reasonable prices. My wishlist is out of control lol!
Noticed delivery has slowed down since first purchase. Last order took 7 days, a longtime in this online age.
Fantastic
Prompt delivery, fabulous price and product. Love my Wella Fusion. Great service- thankyou
I have only used so far to encourage a hot iron curl & its great. Feels nice n soft on my thick coarse grey hair & smells delicious too, which even my partner noticed!! Big Beaver fan.
Does as it says + super sexy shiny! I enjoy the Beaver products on my thick coarse grey hair & at a great price too.
Silly name but great price, smells yum & my thick natural grey coarse hair feels gorgeous after.
If unsure try the 60ml travel size first.
