I used this with the shampoo and although it does work in strengthening, I think this conditioner is really bad. I'm not sure if the strengthening part is because of the conditioner, but this product doesn't moisturize my hair well. My hair tangles quite easily and is pretty frizzy but maybe that was the effect of 16 years of sulfate shampoo. Would buy it again until I can find a better substitute, though.
I bought this for a few bucks (maybe $2.50) at Big Lots. I was surprised they had an all natural conditioner there so I thought I would try it out. I've never said this about a product before, but this is a confusing conditioner. I bought it during winter, but stopped using it because it wasn't moisturizing enough. I started using it again now (almost summer) and it does provide light conditioning (which is all I need because my hair gets oily during the hot summer months). It also makes my hair slightly stiff (this is the confusing part). I don't know if I should use more or less of the product so the stiffness will go away. In any case, it doesn't seem to be weighing my hair down, making it oily, or irritating my scalp, so I'll keep using it until the bottle is used up. Right now I wouldn't repurchase it, but after a few weeks of use maybe my hair will be stronger (because of the biotin). If my hair is noticeably improved after weeks of use I would repurchase it.
EDIT (6/14/11): I kept using this conditioner and something changed, my hair isn't stiff anymore. I'm using the same shampoo so I don't know what happened. I would repurchase this conditioner again if I saw it on sale. I like that it is all natural and that it provides light conditioning in hot/humid weather.
I bought this during a holiday in Australia hoping to find something to nourish and strengthen my 20% grey, coloured, over processed medium-thin hair, knowing that it may be not moisturising enough. It was a nice surprise to find out that it is really moisturising without coating my hair. Even if I use it on the roots (what I recommend, being full of natural substances, good also for the scalp) my hair are bouncy, smooth and fresh also the next day. Good for every day especially in summer, due to the refreshing mint tangling effect. The only problem is that it is not easy to find it in NZ - and not at all in Europe.
This is an inexpensive, natural based conditioner. I like that biotin is listed as the third ingredient. Has a peppermint scent and mild tingle that I like. I have been using this daily for the last three months. It works well for my fine, dry hair. Contains amino acids, protein, and herbal extracts.
