Recently I was asked, "Which products can you recommend for dry hair in this long, hot Houston summer?" That is a very good question and one that not many people think to ask. While we all know how important it is to use sunscreen to protect our skin, we do not often think about the effects of the sun on our hair.
The summer heat can dry the hair much the same way that blow dryers and curling irons do. The stronger UV rays also penetrate the hair shaft and damage the melanin or pigment of your hair. This is visible in the "sun bleached" effect you see as your hair becomes lighter with prolonged exposure to the sun. Unless you take precautions to protect your hair, it can become dry, frizzy, brittle and harder to manage.
The most obvious way to protect your hair is to decrease the amount of time it is exposed to damaging UV rays by wearing a hat as much as possible. This is especially helpful mid-day when the sun is the hottest. For times when it is not possible to keep your hair covered, using an SPF sunscreen for your hair is recommended.
Although there are some shampoos and conditioners that claim to have SPF properties, they are not as effective because you must rinse them off. The best products are leave in conditioners that contain sunscreen. Quintessence Q-Sunshade Leave In Hair Conditioner and Scalp Protectant SPF 30 has one of the highest SPF ratings of any of the prepared hair care products I have found.
Alternatively, you can make your own sunscreen for your hair and scalp. Simply dilute a couple of teaspoons of your favourite sunscreen product with water in a spray bottle. Spritz it into your freshly washed hair before styling. Carry a small misting bottle of this mixture with you and apply another light spray to your hair if you plan to be in the sun for an extended period of time the same way you would apply additional sunscreen to your skin.
Once per week you should use a clarifying shampoo to remove any build up of sunscreen from your hair. At this time, it is also a good idea to do a deep conditioning treatment to replenish some of the moisture lost. One of the best deep conditioning treatments for your hair is a hot oil treatment. You can make your own using olive oil, jasmine oil or jojoba oil and vitamin E. Just poke a couple of vitamin E tablets with a pin and squeeze them into a ¼ or ½ cup of oil and mix with a small amount of very hot water in a jar. Put on the lid and shake to emulsify the oil. Place on your hair while still warm. Place a plastic cap or plastic wrap around your hair and leave in for a minimum of 30 minutes. If you can leave this on your hair overnight it is even better. After the treatment, wash your hair and style as usual. You will find your hair to be smooth and shiny and appear full of life again.
It is important to understand that you cannot completely repair hair once it is damaged. All you can do is prevent further damage and help to make the damaged hair more manageable. Hair has a top layer that resembles scales. In healthy hair the scales lay flat and the hair strands appear smooth and shiny. In damaged hair these scales will curl making the hair appear frizzy and brittle and full of split ends. Deep conditioners can help to coat the hair to make it appear smooth again, but it cannot fully cure the damage. Only cutting the hair to remove the damage will completely get rid of it. Therefore, using the sunscreen and keeping your hair covered whenever possible is the only way to prevent the damage from happening in the first place.
One last recommendation that was passed along to me from a chemist who has formulated dozens of hair products over the years is to use a dime sized amount of "Downy Fabric Softener" twice a week to condition the hair. You will be amazed with the results. Try it for yourself and you will see.
