It is often thought that the thicker the shampoo, the more nutrients it contains. But is that really the case?
The main ingredients of a shampoo are water, surfactants, conditioner, thickener, functional aids, essence, preservative and pigment, and water is the most abundant. Therefore, the original texture of a shampoo is liquid, it is only after thickening agents like sodium chloride have been added that a shampoo shows a thick texture.
Generally, we can evaluate a shampoo from the following aspects.
Texture and smell
Whether being thick or thin, a good shampoo is always fine in texture and does not contain foreign matter, with a natural fragrance that makes people feel pleasant, relaxed and refreshing.
People know how mild a shampoo is from its pH value. Our scalp is weakly acidic with the pH value 4.5 to 5.5. The healthy hair has complete and tractable cuticles, which are easy to be damaged by the shampoo that is with strong alkalinity. While the shampoo that is weak acidic can help keep the acid-base balance on the scalp and make hair smooth.
Foaming effect can be used as a criteria to evaluate a shampoo. While it is worth noting that the amount of foam is not equated to the detergency of a shampoo, because there are surfactants (like amino acid surfactant) producing less airy foam, but they have good cleaning power.
The main function of shampoo is to clean the scalp and create a good growing environment for hair. The cleaning power of a shampoo is determined by the surfactants it adopts. Amino acid surfactants are relatively weak, but milder and less irritating.
The continuously hot-selling feisou NOURISHING SMOOTHING shampoo adopts amino acid surfactants with the pH value of 5.5 to 6.5, which is as weakly acidic as human skin. It removes the grease and dirt from hair without leaving a dry and tight scalp. People with sensitive scalps can also use it at ease.
The natural nutrients such as jojoba seed oil, tangerine peel oil, squalane, hydrolyzed keratin in this shampoo can nourish dry and unruly hair, making it soft, smooth and shiny. Having a good foaming effect, the shampoo is pure and thin in liquid (not containing any thickener), and the natural sweet smell of it comes from the orange peel oil.
Concentration is not the criteria to evaluate a shampoo, feisou has proven it to people.
