A: Hi A! Thanks for reaching out about Garnier Fructis Sleek & Shine Sleek & Stay Heat-Activated Hair Serum. For optimal results, apply 1 pump of the product at a time to damp hair after shampooing and conditioning. Depending on your hair type and washing frequency, you may need to adjust the amount used. The product's effectiveness is maximized by heat activation using a blow dryer or flat iron. However, it can be used on dry hair.
