One of the coolest things about co-washing is that it can help to reduce tangles and knots in your hair. This is because conditioner is typically more gentle and hydrating than shampoo, which can strip your hair of its natural oils. By using conditioner as a wash, you can help to detangle your hair and make it feel softer and more manageable.
Another benefit of co-washing is that it can help to preserve the natural oils in your hair. When you use shampoo, it can strip your hair of its natural moisture, leading to dryness and damage. Co-washing helps to avoid this problem by using a more gentle and nourishing approach to cleaning your hair.
But here's the thing: co-washing isn't for everyone. If you have oily hair, you may find that co-washing makes your hair feel greasier and more weighed down. This is because conditioner can be quite rich and moisturizing, which can be too much for hair that's already prone to oiliness.
