Finally the favourite hair spa we can work on right? Beer is an excellent conditioner because of the malt and hops which are used to prepare the beverage. These add volume to your hair and deep condition it. This is a very good hair spa for dry and damaged hair. All you need is a bottle of beer. Open the bottle of beer and let it sit overnight so that it goes flat. Wash your hair with a mild shampoo and instead of the conditioner, use the beer. Pour it over your hair and massage it into your hair for a few minutes. Rinse with cool water and air-dry your hair.
