Why you don't need to care about co-washing


Co-washing, short for conditioner washing, has hit the headlines once again this year. Favoured by women with curly or dry hair, it seems to offer a solution to dreaded dryness and frizziness. The theory is that by skipping shampoo before conditioning less of the hair’s natural oils will be stripped. Therefore, the hair can retain its own moisture and develop a lovely healthy natural shine.

The idea that washing your unmanageable hair could take less time and could be easier to style is pretty tempting. It’s understandable why the trend for co-washing resurfaces every few years. Nonetheless, the old adage is true: if something seems too good to be true, it usually is. People who choose to co-wash may stop cleansing their hair and scalp completely and just use a conditioner when washing their hair. However, many co-washers are using special cleansing conditioners which promise to cleanse the hair enough, without having to use shampoo prior. It sounds pretty simple but co-washing isn’t for everyone. We have collated some of its disadvantages and hope to show you how KeraStraight can tackle your unmanageable and dry hair, co-wash free!

The drawbacks of co-washing

Unfortunately, the new cleansing conditioners that are on the market may not be enough to rid the hair of product build-up. This can result in the hair becoming heavy and dull, which is the opposite of the effect many co-washers are looking for. There has even been a major lawsuit involving over 200 women, who reported that their cleansing conditioner caused severe and permanent damage to their scalps and affected their hair growth! Of course, co-washing doesn’t always result in extreme reactions like these, but it serves as a reminder that we need to carefully research our own choices when it comes to caring for our hair.

So what is it about shampoo that the co-washing community is so adverse to anyway? Many shampoos contain ingredients such as sodium lauryl sulfate or laureth sulfate (SLS) which are used to create foam and cut through grease. This combination is often used in other products such as washing-up liquid, so it’s easy to see why so many people aren’t keen to use them on their hair. SLS based products might be great at cleaning dirty dishes, but over-cleansed hair can become even drier and unmanageable.

If you’ve struggled with frizz or have dry, coarse, or damaged hair the search for something that fits into your daily routine might feel never-ending. Don’t worry, we’re here for you. KeraStraight has the solution.

An alternative to co-washing is using a shampoo and conditioner that is free from SLS such as the KeraStraight Moisture Enhance Shampoo and Conditioner. These products are free from harmful ingredients such as sodium chloride, sulphate and cocamide DEA, but still foam. Our special formula cleans the hair whilst also hydrating and smoothing the cuticle.
