Hair is complex. It's made up of three layers and thousands of cells. But the reason it gets frizzy is pretty simple. Your hair's outer layer, the cuticle, looks kind of like a shingled roof, dermatologist Carolyn Jacob, MD, says: ''When hair is smooth, those shingles lie flat. But when you run a brush through dry, curly hair, those 'shingles' lift.''
To compound the problem, stylist Dennis Baker, says: ''Frizzy hair is often drier and naturally tends to absorb moisture from humid air. Again, those “shingles” lift.''
8 Quick Tips to Keep Hair Frizz-Free
1. Don't brush dry hair. If there's one tip repeated by just about every expert, it's this: avoid brushing hair after it dries. Brushing not only disrupts your hair's cuticle, it can also stretch hair, leading to breakage.
Instead towel-dry hair after a shower, Don't brush, add a touch of your preferred conditioner or anti-frizz product and leave hair dry naturally.
2. Comb dry hair with wet fingers. If you shouldn't brush, what can you do when humidity or a brisk day leaves your hair a frizzy mess? Water is the key.
3. Tame with a touch of conditioner. To eliminate the frizz, water down a bit of hair conditioner and then using your hands to apply it to just the tips of your hair.
4. Look for protein in your conditioner. A protein-infused conditioner will both manage frizz and create shine.
5. Don't over-process hair. Relaxers and straighteners can make hair brittle and lead to breakage.
6. Put moisture back in your mane. Frizzy hair tends to be drier, so you need to put moisture into it. Use a conditioner, a natural oil, or a frizz cream. Natural oils are better than synthetic because they are absorbed into the hair. Synthetic silicon moisturizers, on the other hand, lie on top of the hair, making it appear dirty.
7. Use a hair recovery masque. For more info check this tutorial:
