Nellen Extender (Anti-Frizz) Shampoo and Conditioner 2-Pack with Keratin · Salt, Paraben & Sulfate-free

I don’t normally write reviews but I’m so utterly disappointed by these products that I felt I had to. The shampoo is useless barely foams unless I use loads and I have a short bob so the fact it’s such a small bottle means I’m going to go through it quickly and I only wash my hair every four days. The conditioner does absolutely nothing. My hair is coloured and it’s like straw when I’ve washed it with these products. Will not be repurchasing and have had to stop using the conditioner.

Lovely shampoo and conditioner. I have a keratin straightening treatment on my hair and brought these because they are salt free. They compliment my keratin treatment really well. I leave the conditioner in for a few minutes before washing out and it leave a smooth finish and reduces frizz. I will be continuing to use it.

Not a pleasant texture and conditioner is very liquid, doesn’t do good job at all

The shampoo and conditioner had a nice smell and worked well with my hair.

It works excellent after treatment protein

I have really curly hair and am always looking for new products to limit or get rid of my frizz. So when I saw this products of shampoo and conditioner, I thought id give it a go. I have been pleasantly surprised. AFter one use I didn't really notice a change however, after 2 uses (I wash my hair every 2-3 days) I noticed my hair felt a lot sleeker. When I straighten my hair normally it is quite fly away however now it seems to stay straighter and less frizzy for a lot longer. You can tell when you are suing the products (in the shower) that your hair feels a bit drier - but no dried out just a bit cleaner with less moisture in it. I really like both the shampoo and conditioner and will continue to use as my hair is a lot less frizzy now a - I would go as far to say not frizzy at all when straightened.
