98% of shampoos contain DEA/MEA and/or Sodium or Aluminum Laureth Sulfate (SLS) derivatives. These chemicals were designed as engine degreasers. If their sole purpose is to strip oil away from an engine, what do you think they do to your hair?


Our goal is to promote hair health without the use of harsh, damaging chemical additives found in most cleansing products. By blending mild, non-irritating cleansing agents with water soluble polymers, we have created a product so gentle that it can be used daily. The unique formula removes scalp residue and build-up without stripping the hair of its natural oils which are essential for optimal hair health.


HRI Hair Therapy DHT Shampoo also contains DHT blocking ingredients to minimize hair shedding and to restore the appearance of fuller, thicker, and healthier hair. The hormone DHT is the primary cause of aging hair, attacking hair follicles and causing them to die.  DHT is the primary cause of aging hair.

HRI Hair Therapy is DEA and SLS FREE


DEA is used as a wetting agent in shampoos, lotions and cosmetics and is widely used because of the rich lather and consistency it provides. According to several studies, while not harmful on its own, DEA can react with other ingredients in the cosmetic, creating a potent carcinogen called nitrosodiethanolamine (NDEA). NDEA is absorbed through the skin and has been linked with stomach, esophagus, liver and bladder cancers.


SLS is used to break down the surface tension in water and is also found in soaps, detergents, creams, and cleansers, but is a mutagen and a potential carcinogen.  Stored in the liver, heart, lungs or brain, SLC can cause skin inflammation, hair loss, tooth decay, and damage to the eyes.  Clinical studies also demonstrate that DEA and SLS reflect away laser light and lessen the effects of laser light therapy.
