Lovely shampoo, I'm sure my very fine hair is thicker since I began using it. Seems to be growing fast as well!

This is the best shampoo

Originally posted on SMCK Hair Care Products Limited

This is the best shampoo I have used since I've got older (I am 78). My hair is thin and fine but this shampoo gives it lift and volume. It also makes it shine. The only gripe I have is the bottle. My hands are arthritic and I find the bottle too firm to squeeze the shampoo out

Works well for cleaning but not volume.

Cleans my hair and gives me shine but still left with very fluffy fine hair however am getting on in years so maybe thats why. I use the whole range of cool girl but no miracles for me sadly but lovely smell and lasts well.

Makes my hair thicker and more textured

I have been using various products now for nearly a year - I have found them so much better than any others on the market and they really make my fine hair look textured and much thicker - I am very happy with them

To use the whole range is very beneficial, it gives lots of volume which lasts for days.

Heavenly! Bought this travel size to take away on a trip (was a risk but hey, I’m adventurous!) and was delighted with the result.

Lovely shampoo, feels good...

Originally posted on SMCK Hair Care Products Limited

Lovely shampoo, feels good and keeps the hair looking good. It would have been 5 stars but the dispensing lid doesn’t work so I have to remove it to get the shampoo out which is irritating as I tend to get too much out doing that. Product is great, packaging not so good. Will buy again and perhaps try to find a dispenser to transfer into.

Great

Originally posted on SMCK Hair Care Products Limited

Hair was nice and shiny on first use, also very manageable. Really like it. Only complaint which lost one star was that I couldn’t get the pottle open to use it. Didn’t know it had a clear seal on it and being partially sighted couldn’t see it. Otherwise great shampoo

Good shampoo, faulty container?

Originally posted on SMCK Hair Care Products Limited

I like the contents, the shampoo that is, but I can't get the indentation on the top of the container to open the little hole to dispense the product. I have to unscrew the top and that probably means I use more shampoo than is necessary.
