My main issue is frizz and puffiness in humid weather. How exactly do the ingredients in this serum help with that, and how should I apply it for the best anti-frizz effect? — serum for curly hair, 30 ml-VICTORIA BEAUTY

The formula addresses frizz through specific conditioning agents—guar hydroxypropyltrimonium chloride and quaternium-98. These ingredients work by coating the hair surface with a thin, smoothing film. This film helps to seal the cuticle layer, which reduces the hair's ability to absorb excess moisture from humid air, a primary cause of frizz and puffiness. The film also improves slip between strands, helping them separate neatly instead of expanding into a fluffy cloud.

For the best anti-frizz effect, application timing and placement are key. Use it on damp, freshly washed hair, ideally after you've applied any leave-in conditioner or cream. Distribute a small amount (a pea-sized drop to start) evenly through your mid-lengths and ends, avoiding the roots if your scalp is oily. You can use your fingers or a wide-tooth comb. For extra definition and frizz control on dry hair, you can take a tiny amount (less than a pea) rubbed between your palms and lightly smooth it over the surface of your dry hair, focusing on areas that tend to frizz first. Because it's a leave-in serum, this smoothing effect continues after drying. Remember that very porous or coarse hair might require a slightly larger amount, while fine hair often does better with less to avoid looking greasy.
