Selsun Blue

Selsun Blue is a widely recognized brand of anti-dandruff shampoo that contains the active ingredient selenium sulfide. It is used to treat dandruff and seborrheic dermatitis of the scalp. Selsun Blue is known for its distinctive blue color and is available in various formulations to cater to different hair types and scalp conditions.

History

Selsun Blue was first introduced in the 1960s by Abbott Laboratories. The product quickly gained popularity due to its effectiveness in treating dandruff, a common scalp condition characterized by flaking and itching. In 2002, the brand was acquired by Chattem, a subsidiary of Sanofi, which continues to market and distribute Selsun Blue globally.

Active Ingredient

The primary active ingredient in Selsun Blue is selenium sulfide, a compound that helps reduce the production of natural oils in the scalp and slows down the growth of yeast that can cause dandruff. Selenium sulfide is effective in treating both dandruff and seborrheic dermatitis by reducing flaking, scaling, and itching.

Formulations

Selsun Blue offers a variety of formulations to address different hair and scalp needs:

• Selsun Blue Moisturizing: Contains added moisturizers to help prevent dryness and maintain scalp health.
• Selsun Blue Medicated: Provides maximum strength treatment for severe dandruff and seborrheic dermatitis.
• Selsun Blue Naturals: Infused with natural ingredients such as aloe vera and chamomile for a gentler approach.
• Selsun Blue Itchy Dry Scalp: Formulated with menthol to soothe itching and irritation.

Usage

Selsun Blue is typically used two to three times a week, or as directed by a healthcare professional. Users are advised to wet their hair, apply the shampoo, and massage it into the scalp. It should be left on the scalp for a few minutes before rinsing thoroughly. Overuse or improper use can lead to scalp irritation or increased oiliness.

Side Effects

Common side effects of Selsun Blue include mild scalp irritation, oiliness, or dryness of the hair and scalp. Rarely, it may cause allergic reactions such as rash, itching, or swelling. Users should discontinue use and consult a healthcare provider if severe side effects occur.
