Besides cold winds against the skin, winter weather affects hair as well. The temperature changes and dry air start to make hair brittle and weak. While lounging in front of a warm fire over break try one of these easy, at-home hair treatments to get hair back in top condition for all of those holiday parties.

The olive oil treatment:

This treatment replenishes dry hair and protects it against further breakage.

Warm up a few tablespoons of the oil on the stovetop. Make sure the oil doesn’t get too hot or warms to a boil because it will be going directly onto the scalp. Dip hair into the pan or pot as far as possible. Once the oil has cooled down, pour onto the scalp. Massage the oil around in an effort to cover the entire head. Wrap hair up in a warm towel and leave for a minimum of 30 minutes.

Other oils such as coconut, almond, corn, lanolin and castor are all acceptable as well.

The mayonnaise treatment:

This treatment gives hair a shiny, healthy appearance.

As Blake Lively has recently revealed, she uses mayonnaise on her hair for protection against the effects of shampoo. In a Popsugar interview she said, “My mom taught me this really great beauty tip. She used to put oil or mayonnaise on the bottom half of her hair before she would shower. That way, when she would shampoo, the soap wouldn’t strip the bottom of the hair and dry it out, making it brittle.”

For a different take on the treatment, slather half of the condiment onto the hair and scalp. Cover head with a shower cap or dry towel and leave for at least 30 minutes.

The avocado, egg and honey treatment:

This treatment works as a deep moisturizer to strengthen and nourish.

Mix together one avocado, two eggs and one half tablespoon of honey or oil. Spread the mixture throughout hair up to the scalp.

Wrap hair up and cover with a shower cap for at least 30 minutes.

After all of these treatments, shampoo hair two to three times with lukewarm water. Leave extra time in the morning to shampoo again if products are still visible in hair.
