Sun blocks are used to block the UV rays of the sun from penetrating the skin. The metallic material in the sun block reflects and scatters the UVB rays thus shielding people with sensitive skin.
Zinc oxide and titanium dioxide form the main ingredients of sun blocks. These ingredients protect the skin from UVB and UVA rays. Sun block is not absorbed completely into the skin; it remains on the surface. Homemade natural sun blocks are an option to consider as against chemically loaded ones available in stores. Natural sun blocks can be used by people with sensitive skin too.
Many people do not prefer sun block as it opaque and can get quite messy. Sun block lotions tend to stain clothes. They are not absorbed into the skin and are likely to show.
Natural sun block recipe
Pick a bottle of your favorite natural lotion, one without citrus oils. Add a couple of tablespoons of zinc oxide. Take care that you do not inhale the zinc oxide. Mix ingredients.
Oil based sun block
Coconut oil 1/3 cup
Zinc oxide 5 tsp
Vitamin E oil 2 capsules
Beeswax 1 tbsp. (for thicker consistency you may use more quantity)
Distilled water ½ cup
Natural aloe Vera gel 3 tbsp., use alcohol free gel
Essential oils that are not citrus oils can be used to improve the fragrance of the sun block. Mix ingredients well.
Cocoa butter sun block
Use a double boiler to melt and mix sesame oil, cocoa butter and bees wax. Stir with a spoon until the mixture reaches a smooth consistency. Remove the double boiler from heat and add the distilled water to the mixture. Break open the Vitamin E capsules; add the oil to the mixture. Add the zinc oxide and rosemary tincture to the mixture until thoroughly blended. Allow the sun block recipe to cool before transferring it to a storage container with a lid. Store the homemade natural sun block in the refrigerator.

Sunblock for hair
It's just not the skin but also the hair that gets affected by the harsh rays of the sun. As we protect the skin from the sun, so also we must protect the hair from harsh rays of the sun. The UV radiation can make the hair dry, rough, greasy and can even cause split ends.
Sun blocks protect the hair cuticle, the upper most layer of the hair. They form a coat and do not allow the sun rays to penetrate deep into the hair layers. The coat reflects the sunlight and heat instead of absorbing it. They repel the radiation. Titanium dioxide and zinc oxide are commonly used in sun blocks.
Sun blocks for the hair are available as creams, sprays, etc. Massage the creams onto the hair or spray them on. While picking a sun block for the hair, remember:
Sun block SPF
SPF means Sun Protection Factor of sun block or sunscreen. The SPF numbers, multiplied by 10, indicate the number of minutes that the Sun Block will offer protection against the sun rays. SPF is a measure of a sun block's ability to prevent UVB from damaging the skin.
In general no sun block offers complete protection and cover against the harsh rays of the sun. It is advisable to reapply sun block every two hours. Sun blocks are not just for the sunny days. You need sun protection even on cloudy days or in the cold. In fact, snow reflects UV rays. Apply the sunblock to all exposed areas of your skin. You need to apply the sunblock about 20 minutes before venturing out in the sun.
