That is a great question and kudos to you for considering it. After making an investment in your hair, whether it be all-over color, highlights, lowlites, etc., it is important to chose products that will safeguard your hair, protecting it from fading and damage.
To maintain beautiful, shiny, bouncy and healthy hair, the proper balances of pH, protein, and moisture are essential. Just a few things that can make these essentials fluctuate are environmental factors, chlorine and minerals in bathing water, and coloring your hair.
If you want your hair to be healthy and your color to be long lasting, vibrant and shiny, you must use products on a regular basis that are specifically formulated to return your hair back to its ideal pH level. This is between 4.5 - 5.5. The reason this is so important is because it provides a "seal" around the hair's delicate cuticle.
Choose an organic shampoo and conditioner that have been formulated to provide that perfect pH balance - using 100% organic and natural ingredients - like moisturizing aloe vera and apricot oil. Avocado oil is another great moisturizer that has natural sunscreen properties that can protect the hair from harmful UVA & UVB rays. Hemp Oil, being a perfect gluten-free alternative to wheat, is loaded with protein that contains moisture balancing properties, helping to maintain beautiful & healthy hair.
As a professional 'organic' hairstylist that has specialized in coloring hair for 14+ years, it was extremely important for me to not only find a healthy product line to use and recommend to my color clients, but also one that would hold up to the highest performance standards as well. This is the biggest reason why we decided to create the first ever 100% pure, professional line of haircare products, called Shear Miracle Organics. In fact, every shampoo and conditioner, with the one exception being our 'clarifying' shampoo, has been created to keep your hair color (whether natural or professionally done), in perfect shape! Many of them even say "Save Your Color" right on the bottle! Since you specifically mentioned highlighted hair, I want to let you know that we use two ingredients that are favorites amongst blondes: calendula, which is especially beneficial to blonde hair and chamomile, which brings out natural highlights.
