Description

Shampoo and preparation method thereof

Technical Field

The invention belongs to the technical field of daily cosmetics, and particularly relates to shampoo and a preparation method thereof.

Background

At present, due to the fact that life rhythm is too fast, working pressure is too high, and environmental pollution is serious, a lot of people have the problem of scurf. Dandruff is produced mainly by a fungus called malassezia, which proliferates on the scalp in large quantities and causes excessive growth of the stratum corneum of the scalp, thus promoting abnormal desquamation of stratum corneum cells in the form of white or gray scales to form dandruff. Malassezia serrata survives after absorbing fatty acids from sebaceous glands, and after saturated fatty acids decomposed from triglyceride in sebum are consumed, the residual unsaturated fatty acids permeate into scalp again, so that scalp inflammatory reaction is caused, the inflammatory reaction accelerates the formation of dandruff, and the circulation is repeated, so that more and more dandruff is caused.

Generally, the dandruff removing shampoo is mainly added with zinc pyrithione, ketoconazole, climbazole, pyridylethanolamine and the like for bacteriostasis so as to achieve the effect of removing dandruff, but the addition of a large amount of the dandruff removing agent has large stimulation to the scalp, and the hair is easily frizzy and rough.
