Description
Technical Field
The invention relates to the technical field of daily necessities, and particularly relates to an anti-dandruff and anti-itching shampoo and a preparation method thereof.
Background
Dandruff is the exfoliative corneocytes of the scalp. Normally, keratinocytes shed very little, slowly and are not seen significantly. However, under certain stimulation, a large amount of immature keratinocytes are produced, agglomerated and shed, and a phenomenon of 'snowflakes', namely dandruff, which is raised in a dispute is formed. During dandruff formation, two substances play an important role: oil and fat secreted from the scalp, and fungi that feed on oil and fat. Under certain conditions, such as when the grease secretion in adolescence is strong, fungi can be proliferated on the surface of the scalp in a large quantity, and scalp cells are stimulated to secrete more grease; a large amount of grease provides nutrients for further amplification of fungi. Finally, the normal scalp stratum corneum cell metabolism becomes unstable, and immature keratinocytes aggregate and fall off in a row, and dandruff is generated.
At present, chemical agents capable of relieving itching, such as ketoconazole, zinc pyrithione, 0 topirox and 17-hydroxy-BETA-steroid dehydrogenase, are mainly added into shampoo to achieve the effects of removing dandruff and relieving itching, and although the chemical agents can rapidly remove dandruff, the chemical agents can also cause scalp intolerance, have great damage to scalp, and are not suitable for frequent and long-term use. In recent years, shampoo containing traditional Chinese medicine additives has been researched, but the problems of poor anti-dandruff effect, more added traditional Chinese medicine components, single effect, complex process and the like exist.
