How to Co-Wash Your Hair Without Wrecking It

Co-washing means cleansing with conditioner instead of shampoo—massage into scalp for 2-3 minutes, focus on roots, rinse thoroughly.

1. Wet hair completely. Saturate every strand with warm water. Cold water won't open the hair cuticle enough for proper cleansing.
2. Apply co-wash to scalp. Use a quarter-size amount and work it directly into your scalp with fingertips. Skip the lengths for now—your scalp is where oil and buildup live.
3. Massage for 2-3 minutes. Really work those fingertips in circular motions. This is doing the job that shampoo's surfactants usually do—breaking down oil and debris.
4. Distribute through lengths. Now pull the product through your hair from mid-length to ends. This conditions while gently cleaning the hair shaft.
5. Rinse until squeaky. Rinse longer than you think you need to. Co-wash leaves more residue than shampoo, and buildup kills the whole point.
