I have naturally wavy hair and with the humidity this season they turn into a frizzy mess. I've tried various serums but nothing that really works. Can you recommend a good product that won't weigh them down too much?
It's not that serum is really the right solution for frizzy wavy hair - it usually just weighs it down even more 😅 Instead try a lightweight anti-humidity spray (the kind you spray on wet hair before blow-drying) or a dry oil made specifically for curly/wavy hair, that nourishes without looking greasy. But honestly the real difference comes down to how you dry it: with a diffuser and smoothing products applied to damp hair, not after it's already dry.
Don't use heavy products like dense oils or creamy masks - they'll make frizz worse instead of fixing it. Try a lightweight silicone spray or a serum with polymers specifically designed for moisture in wavy and curly hair, not straight hair. The key is applying it to hair that's still a bit damp so it penetrates better. Honestly, sometimes the secret is also drying your hair the right way: if you use a blow dryer with a diffuser instead of drying it straight, the results change quite a bit.
I'd say pure silicone (the kind in classic serums) can actually help, but you need to find the right product - the problem is when you use too much of it or apply it to damp hair, which makes it sticky. Try an ultra-lightweight serum (like those in clear liquid format, not creamy) that you apply only to the lengths and ends of dry hair, maybe the night before; or look into leave-in sprays in a very liquid version, because they keep the lightness you're after.
But the drying routine is also crucial - if you blow dry randomly the frizz wins anyway. Better to dry against the grain to seal the cuticle and calm down the effect.
