I have grey naturally curly hair. I only wash once a week, using conditioner only - if you are accustomed to washing more frequently, stretch the gap between washes a day each time. Wash once with an ordinary shampoo to remove the residue of silicone from your hair. From then on, wash with silicone-free conditioner. I use Garnier Ultimate Blends coconut water conditioner, but I know Sainsbury’s own brand coconut conditioner is silicone-free. Quite a few brands now put ‘silicone-free’ on the label.
I just wrap it in a towel while I dress, then shake my head and let it dry naturally without heat. I have a good cut every 8 weeks. I can’t persuade my hairdresser to use silicone-free and conditioner only, so for the first wash after a haircut I use baby shampoo to remove the silicone.
I don’t even need to brush it each morning. I can get away with running my fingers through it when I get up.
