For best results, allow 2–3 shampoos in between uses of this volumizing treatment for fine hair. Usage in this manner effectively produces hair texture–enhancing results without build-up. However, results may vary based on your individual shampoo habits and hair texture preference. We do not recommend that you use the treatment every day, in order to allow hair to return to its normal texture between washes. Using as directed preserves the product's effectiveness and prevents build-up.
