If you suffer with dandruff try this shampoo bar and you will never use your prescription shampoo again. Many medicated dandruff shampoos often provide only temporary relief and usually end up irritating your scalp. Dandruff is caused by malassezia, a yeasty fungus that normally lives on the skin, and if this fungus becomes too prevalent it will create dandruff. An effective and natural remedy for dandruff is Tea Tree oil, which is derived from the Tea Tree and is well known as an effective antifungal and antiseptic. Use this shampoo bar on your hair and scalp for deeply cleansing and anti-dandruff effects. If you have color treated hair you will need to test the shampoo bar first on a small section of your hair. It may take your hair one week to get used to this soap but the end results are astonishing. This listing is for one, wrapped and labeled bar, weight approximately 4.5-5 oz.
