What is Selsun Shampoo 2.5% (Selenium Sulfide)
Selsun Dandruff Shampoo is a medicated shampoo used to treat the scalp from dandruff and seborrhoeic dermatitis. It is effective in reducing grease on the scalp and helps with slowing down the process of newly grown skin cells.
The skin on the scalp is more sensitive than any other part of our body and grows skin cells at a faster rate. It is made up of tissue layers that contain more hair follicles and sebaceous glands. Selsun Dandruff Shampoo 2.5% reduces the growth of the grown tissues and improves nourishment for the hair to grow at a healthier rate.
Using this anti-Dandruff Shampoo on a regular basis helps the tissues on the scalp stay longer and keep the skin cells more connective thus healthy. This product is safe for anyone over the age of 5. This Shampoo is considered a pharmaceutical medicine and is approved by the Medicines & Healthcare Products Regulatory Agency.
How Effective is Selsun Dandruff Shampoo?
Selsun Dandruff Shampoo contains 2.5% Selenium Sulphide. Selenium Sulphide is excellent at killing a type of fungus known as Dermatophyte. Eliminating Dermatophyte helps with the prevention of cutaneous mycoses, also known to cause nail and hair infections. Selenium Sulphide is classified as an anti-infective, which works by slowing yeast growth that causes various infections. This active ingredient is reported by a Journal of Dermatology to be effective in reducing cell turnover and has anti-seborrheic properties. It is considered a powerful anti-dandruff active ingredient and is found in many anti-dandruff treatments.
With Selenium Sulphide as its active ingredient, Selsun Dandruff Shampoo provides an anti-bacterial and healing effect on people prone to dandruff. However, you may experience slight oiliness, which is a common reaction to Selenium Sulphide for some people.
Can I Buy Selsun Dandruff Shampoo online?
