Soap to Shampoo
Even though it may sound unusual, individuals used a bar soap to wash their hair until the mid-1930s. Everything changed when liquid coconut oils were made available to produce soap. As a result of the oil's assistance in liquifying the soap, shampoo (also known as liquid soap) was eventually produced. Evolving from washing with soap to shampoo the first non-alkaline shampoo was formulated and introduced in 1933. Drene was the first shampoo to be made with synthetic surfactants. One of the earliest shampoos first formulated as pH balanced was by Dr. John Breck. Shampoos have evolved with technology and tailored for various hair types and scalp conditions.
The cleaning compounds known as surfactants have taken the place of soap. They work by lessening the physicochemical adhesion forces that hold residues and contaminants to the hair. These contaminants are dispersed by surfactants, which stop them from adhering to the shaft or scalp. The effectiveness of a shampoo's washing action is influenced by the kind and quantity of surfactants it uses, as well as how well it eliminates grease.
The demand on professional shampoo ranges is intricate in terms of product comfort and needs of consumers. Shampoos are required to moisturize hair, to produce lather in both hard and soft water, to be delicate on skin and mucous membranes when applied to oily hair, to be chemically and physically stable, to be biodegradable, and to be reasonably priced.
Professional shampoos can help prevent hair damage in addition to cleaning the scalp. Shampoos have 10 to 30 active ingredients. These ingredients are divided into four categories: (1) cleansing agents, (2) comforting additives, (3) conditioning agents, which are meant to add softness and gloss, reduce static, and improve detangling ability, and (4) special care ingredients, which are meant to address issues like dandruff and oily hair.
Hair types that are affected when using aggressive shampoos are, hair damaged by chemical treatments, hair damaged by mechanical damaged such as heat styling tools, hair affected by hormonal conditions, dry brittle hair, and porous hair. Damaged hair types will find difficulty in untangling hair strands and result in more effort to style as usual. Attrition, the main cause of static, frizz and unmanageability in styling hair can be minimized by adequate formulation of shampoos and hair care products. On the other hand, if the shampoo formulas do not present the adequate composition, fibre attrition is aggravated.
Stephen McNeil, a chemical professor at the University of British Columbia, claims that if the sole purpose of your shampoo were to remove oil, it would be identical to your hand soap. McNeil said that the detergent, or SLS, alone, is too abrasive for your hair. Thus, professional hair care companies use gentle cleaning agents and add conditioning agents to shampoos to add shine and manageability to hair.
