Treatments for brittle hair include sour cream or yogurt, honey and avocado. Other methods for treating brittle hair are lowering the heat setting on styling tools, using moisture-replenishing products and washing hair only twice a week.
Sour cream and plain yogurt contain lactic acid and milk fat. The lactic acid removes dirt, while the milk fat hydrates the hair. Coat the hair with either sour cream or yogurt, massaging it into each strand. Let it sit for 20 minutes, then rinse with warm water. Follow with a cool-water rinse.
Honey naturally attracts moisture. Massage the honey into damp hair, and allow it to sit for 20 minutes. Rinse it out with warm water. If the hair shows signs of breakage, mix the honey with an egg yolk and follow the above procedure.
The proteins and oils in avocado help smooth brittle hair while adding nutrients to curb breakage. Select a ripe avocado. Mash half of it until it creates a smooth paste. Apply this evenly to the hair, and let it sit for 15 minutes. Rinse out with warm water.
Heat, whether from the sun or heat styling, are prime causes for brittle hair. Avoid using heat-styling products. Shampooing strips the moisture from the hair, so avoid shampooing hair daily. Select shampoo and conditioner that either replenish moisture or stop breakage, depending on the hair's need.
