Natural Shampoos- The latest consume trend.
Shampoos have traditionally been formulated with synthetic surfactants based on sulfates such as Sodium/Ammonium Laureth Sulfate (SLES/ALES) and/or Sodium/Ammonium Lauryl Sulfate (SLS/ALS) which have come under scrutiny in the marketplace. Although, these materials have been used for over five decades with no real adverse safety effects, it is common to find them associated with toxic impurities such as 1, 4 Dioxane and descriptors such as irritating, harsh and drying. As a result, Marketers have responded to the negative publicity by introducing non-sulfate-based shampoos only to find themselves at a disadvantage both in performance and cost. Bria Research Labs has successfully overcome these formulation challenges by developing state of the art formulations without sulfates, parabens or other controversial ingredients. Now the market trend is changing once more and is demanding products that use ingredients that are natural, more environmentally friendly, biodegradable, and are obtained from renewable sources.
Once again, Bria Research Labs has responded to these formulation challenges and has developed Shampoo formulations that are based on all natural ingredients that have cleaning and conditioning benefits that are unsurpassed and as good as the market leaders that use petrochemicals

Shampoo Reviews and Buying Guide:
Most of us shampoo or wash our hair once a day and periodically we use conditioner (some more often than others).
What brand of shampoo is best?
Most studies show that there is very little difference between the expensive salon shampoos and the cheaper brands found in Drugstores. Shampoos are made to remove excess oil, dead skin cells and dirt from your hair and scalp. Lathering your hair more than once will most likely not get your hair any cleaner and may damage it if done repeatedly. There is on need to lather up twice unless you have exceptionally dirty hair and even then experts say you should focus on your scalp and not scrubing your hair. When hair is wet it becomes more fragile and is open to more damage. The key is rinse out all the shampoo so no remnants are left on your hair or scalp. The ingredients in shampoo vary slightly from brand to brand, but most contain sodium lauryl sulfate and sodium laureth which can cause irritation to your scalp. There have even been claims that some of the ingredients cause cancer over long periods of use, but those claims are unproven at this time.
