If you're looking for a paraben free hair range you can find in a supermarket then look no further than the Sainsbury's Happy Hair Days range. The intensive mask is currently on offer for only £3.32. The normal retail price is £4.99. It's a gentle, intensive conditioning mask without parabens. Coconut oil, pear extract and a proven vegetable protein nourish and soften hair from roots to ends without weighing it down, whilst the coconut and marshmallow aroma smells devine.
