Benefits of Niacinamide for Hair (vitamin B3)

You may use Niacinamide in your skincare routine, but did you know that this powerful ingredient doesn’t just benefit your skin? It can help encourage healthy hair growth too!  Read on to discover the benefits of Niacinamide for hair, and how to use our Niacinamide shampoo, conditioner and scalp treatment in your hair care routine. 

What Is Niacinamide?

Niacinamide is a water-soluble form of Vitamin B3 and an essential nutrient for our bodily function and wellbeing.  

As well as being good for the brain and kidneys, topical Niacinamide is renowned for its skincare benefits, and is used to help treat certain skin conditions, such as acne and eczema. As we discuss below, Niacinamide also offers many benefits for your hair.  

What Does Niacinamide Do?

So, what are the benefits of Niacinamide for hair? They include: 

  • Boosts Keratin Production 

Thanks to its ability to help boost protein synthesis, Niacinamide is thought to encourage the production of Keratin, the main structural component in hair, skin and nails. 

Did you know that your hair shaft is made up of nearly 90% Keratin? Deficiencies in Keratin can lead to flat, lacklustre hair that is prone to breakages. 

  • Improves Circulation 

Niacinamide helps to improve blood flow and circulation. When applied to the hair, it can, provide increased oxygen and other nutrients to the scalp.  

This increased circulation stimulates hair follicles and boosts the scalp’s health, creating the optimal environment to encourage hair growth. 

  • Reduces Inflammation 

Struggling with a dry itchy scalp? Inflammation of the scalp could lead to hair loss or hair thinning.  

Niacinamide for hair helps to control inflammation by soothing both the scalp and hair strands, promoting thicker, healthier-looking hair.  


  • Locks in Moisture 

Worried about dry hair? Niacinamide helps to fortify its lipid barrier, encouraging the production of ceramides which help to lock in moisture, supporting strong, hydrated hair that looks sleek and shiny.
