Our aftercare recommendations, that would be suitable for this colour and style:

1. Maria Nila Color Refresh Spray**: This spray is a game-changer for maintaining the vibrancy and dimension of blonde hair. It's a colour-protecting spray that can be used daily to keep your colour looking fresh and vibrant.

2. Maria Nila Moisture Rich Shampoo**: This gentle, sulfate-free shampoo is formulated to cleanse and nourish dry, damaged hair without stripping it of its natural oils. It's perfect for Wavy Light Ash Blonde hair that needs moisture without weighing it down.

3. Maria Nila Hydrate & Nourish Leave-In Conditioner**: This leave-in conditioner is designed to provide long-lasting hydration and nourishment to dry, damaged hair. It's perfect for detangling and adding shine to Wavy Light Ash Blonde locks.

4. Serenity Classic Essential Oil**: Promotes strong, healthy hair growth and strengthens existing hair when using once a week as a hair treatment.

These products can help to maintain the health, shine, and colour integrity of the Chestnut Balayage Hair. It's always recommended to use a wide-tooth comb or a detangling brush when combing through the hair to minimise breakage and prevent knots.

These are general guidelines, and individual results may vary. Ultimately, it's essential to consider each person's unique features and preferences when we recommend a colour and style.
