Hair + scalp

Glutathione

Also known as Potassium CLA glutathione

A powerful antioxidant made naturally by the body. In hair care, it helps protect the scalp from everyday stress for healthier-looking hair.

What is glutathione?

Glutathione is an antioxidant your body makes from three amino acids. It is sometimes called the body's master antioxidant because it helps recycle other antioxidants like vitamins C and E. Levels naturally drop with age and stress.

What it does for your scalp and hair

  • Helps protect the scalp from free radicals caused by UV, pollution and stress
  • Supports a healthy scalp environment for healthier-looking hair
  • Works alongside saw palmetto and panthenol in a complete scalp routine

How to use it

Our Revitalizing Shampoo, Revitalizing Conditioner and Hair Stimulating Serum all contain potassium CLA glutathione. Use the three together, or try the Hair Stimulating Kit, and massage the serum into the scalp daily. Stick with it for at least three months.

Who it's for

Anyone whose hair looks thinner, duller or more fragile than it used to, and anyone building a scalp-care routine.

Common questions

Is glutathione good for hair?
As an antioxidant, it helps protect the scalp from everyday stress, which supports healthier-looking hair.
Can I use glutathione hair products with other treatments?
Usually yes, but check with your doctor if you are using a prescription hair-loss treatment.
