I've started using the Philip Kingsley Elasticizer as an overnight treatment and I feel like it's working a lot better for a deep condition. My top tips are: 1. Check the price per ml for the product you're using. Currently the larger 150ml tub works out only £11.45 more expensive than the 75ml tube, which saves around £5 by buying the larger tub. 2. Try using a moisturising treatment overnight so you get the maximum benefit = less applications! 3. Make sure your hair is damp before application so the mask absorbs properly!
