Frizz is caused by moisture. Damp, drizzly climates, or humid environments cause hair to absorb moisture and revert to its natural, pre-blowdried state. When hair is damaged it loses its ability to maintain moisture and becomes more porous in the damaged areas - hence, ends frizzing more than newly grown roots (which have undergone less chemical processes). Hair can also be naturally coarser and drier and therefore more frizz-prone, too.
1) If your hair frizzes then don’t be tempted to dampen it down as this will re-hydrate your hair more and cause it to frizz further. The aim is to blow dry it to remove the moisture and re-shape the hair to look sleeker, so instead spritz your hair with a leave-in conditioner, which will protect your hair from air moisture content and humidity and restore its natural balance.
2) Frizz caused by porosity or sensitivy (damage to the cuticle and cortex, or main bulk of the hair,) is crying out for moisture. So, use a twice-weekly deep conditioning mask as its ingredients evens out porosity in the damaged cuticles to leave hair smooth and glossy.
3) A serum or gloss wax will prevent frizz but just use a small amount and scrunch into the ends avoiding the root area. Be careful not to over-use silicone based products such as serums, which can result in a product build up on the hair shaft.
4) Keep the use of electrical equipment to a minimum if you want glossy, movie star hair! If your hair is frizzy, blow dry it from wet (not towel dried) as the blow dry will stay in longer (it should last 2/3 days if your hair isn't greasy). Section well and use the right brush (such as my Richard Ward Medium Radial Brush £7.99) and a professional dryer and you should find that you’ll also need less daily electrical intervention.
5) Keep the frizz at bay with regular hair cuts to remove split end, which if untreated can travel up the hair shaft resulting in a ruffled cuticle and therefore encouraging a frizzy appearance.
6) Another trick to achieving frizz free curls is to blow-dry your hair straight before your start curling. By doing this you will eliminate the frizz before you begin styling your hair, which will leave your curls looking healthy and luscious with not a frizzy hair in sight! Think Nicole Kidman, who always does this to result in larger, sleeker curls.
