Lovely hydrating protection spray

4 stars out of a maximum of 5

This spray feels thicker and much more nourishing than other heat protection sprays I’ve used. It feels like it saturates your hair with hydration, leaving it feeling lovely and soft and healthy (no mean feat for my frizzy dry hair!) and leave it with a lovely lasting scent. Will definitely continue to use this spray (and will also be taking it on sun holidays to spray onto freshly washed hair to leave to air dry).

Smells lovely.

4 stars out of a maximum of 5

I often let my hair dry naturally but was testing this heat defense spray so I had to dry it for a change. I found it easy to use and it smells great. I used it alongside the shampoo and hair mask. If I were to continue using heat to dry and style my hair I would use this product.

Leaves the hair smelling great

2 stars out of a maximum of 5

I have used this product following Genesis Bain Hydra-Fortifiant Shampoo and Genesis Fondant Reinforcateur Conditioner. Great smell but unfortunately does not help with the frizz or even the hair loss as it suggests. I still have to use a hair cream even if I did not blow dry my hair to make it feel moisturized.

Good rich conditioner

5 stars out of a maximum of 5

I would recommend this conditioner lovely consistency and easy to apply to wet hair also not difficult to rinse out. My hair was very easy to comb after and smell was lovely. A jar of this would last 3 months.

Love love love this spray!

A spray that you feel does it all! Only had this month but love what it's doing to my hair already. I've been struggling with hair loss after having my baby and this has made a nice noticable noticeable difference and cant wait to see where it takes me

This product is great

5 stars out of a maximum of 5

My hair was dry and brittle and even the hairdresser had a good moan about the state of it! After using this just a couple of times, my hair is lovely and soft and not dry at all, looks and feels completely different already! Will definitely be using this all the time!

Perfect to prevent damaged hair

5 stars out of a maximum of 5

An amazing must have from the Genesis range! I spray this before blow drying my hair. Not only does it leave my hair feeling soft and nourished, but it makes brushing it so much easier too! This in return means less hair breaking off. Blow drying my hair usually causes damage and roughness overtime, but with this spray you'll no longer feel this way! It really does provide deep nourishment and keeps my hair shiny and full of life. A little goes a long way and it keeps my hair smelling divine too!

Fantastic

5 stars out of a maximum of 5

I’ve used this product as an alternative to my usual heat defence serum. The fragrance is lovely and goes well with the shampoo. Not too overpowering but the scent does last. Combined with the shampoo my hair maintained it’s shine and helped keep my hair nourished after drying and straightening

Nice product but spray did not work well

3 stars out of a maximum of 5

I really liked the product but I had a small trial size spray which didn't spray properly so it came out in large drops of liquid rather than a finer misting. It did seem to protect my hair but difficult to use . I will probably look to buy a full size one and try it.

Not sure about this

5 stars out of a maximum of 5

Firstly I must say I am not a person who uses lots of products and try to not use my ghd tongs often. I used this to protect my hair and whilst it left my hair non greasy and was easy to brush my hair afterwards .... I did not have the wow moment that would make me swop the product I currently use as I am happy and used to that one. However if I was looking for a product to protect my hair and yet to find the one then maybe worth a try x
