Each person has approximately 100,000 hairs on his head, according to TeensHealth from Nemours, each of which has an outside layer called the cuticle that protects the hair's two inner layers. When these cuticles become damaged, whether by your hair styling tools, the sun or other causes, the hair loses its moisture and becomes dry, which can lead to frizziness.
Equipment
Though they can help to tame frizz, hair dryers, straightening irons and curling irons are the main culprits in drying out your hair, as they suck moisture away with their high heat. To keep your hair healthy and moist, take a break from heated styling tools occasionally. When using curling and heating irons, do not use them on wet hair or the tool's highest heat setting.
When choosing a hairbrush, look for one with natural bristles. Plastic bristles cause static electricity, which can damage hair and make it more brittle. Brush your hair with long strokes from the roots of the hair to the ends. This spreads your hair's natural oils, helping with frizz and dryness.
Products
Fight dry and frizzy hair with oil-based serums, which "Self" magazine's website calls "sports drinks for your hair." These products hydrate and revive hair and create a healthy and soft sheen on the cuticle. Apply the product by rubbing a dab onto your palms and massaging it into the hair in sections. Start with the ends, where your hair is normally the most dry, and work your way up to the roots.
Sunscreen
The sun's UV rays can burn not only your skin, but your hair as well. Purchase a UV inhibitor, and spray it in your hair before spending the day outside. Other options to keep your hair's moisture intact include wearing a hat or braiding long hair.
Frequent Washing
Frequently washing dry hair strips away natural oils. Really dry hair only needs to be washed once a week, according to TeensHealth from Nemours. Instead of washing your hair while bathing, just apply conditioner.
Split Ends
When hair is damaged, the ends will split up the hair shaft. This causes the hair to become frizzy. Avoid split ends by getting your hair trimmed every six to eight weeks.
Home Remedies
Home remedies for dry and frizzy hair include products from the kitchen. Create an avocado mask for your hair by mashing a ripe, peeled avocado with a teaspoon of wheat-germ oil and a teaspoon of jojoba oil. After washing your hair, apply the mask from the roots to ends. Cover your head with a shower cap. After 15 to 30 minutes, rinse the mask out of your hair. You can also create this mask with mayonnaise rather than an avocado, as the egg in the mayo is a good protein for your hair, according to the "Reader's Digest" website.
