To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Ive had my hair highlighted which really damaged it . I was recommended olaplex by my hairdresser, but was told I can do it at home . After doing some research I discovered cureplex which is a similar product but better value . I'm really pleased by how this product has improved my hair , much less frizz and dryness . I wash my hair , apply cureplex when wet and just leave it to dry naturally and wash it out a day or so later . I don't use styling products when I've got it on my hair .
