The best way to get the right colour for you is to look at your skin tone and see what would suit you the most.
Use hair treatments that will leave it looking really glossy and healthy. Opt for a intensive moisturising treatment once a week.
Excess use of shampoo and conditioner is unncessary and could actually end up damaging your hair in the long run.
Before shampooing, make sure your hair is fully wet, this will help the shampoo get into a lather quicker. You only need around a pound size amount of product.
Focus on your scalp when shampooing as it’s the pair of the hair that contains the most oils and as you probably know is quick to get greasy.
