摘要

The visual perception of individually flakes and sebum on the scalp and hair is an abnormal condition referred, in the public domain, to as dandruff and seborrheic dermatitis. More than 50% of adults may be affected by these conditions, which suggest a high socio economical impact, manifested in the loss of self-esteem generating a negative image. This image may be further worsened when hair damages for the excessive exposure to chemicals and environmental aggressions occur. The regular use of appropriate hair cleansing agents (shampoos) and surface lubricating products (conditioners), reducing the presence of flakes and sebum on the scalp, result also of hair benefits in terms of smoothness, softness, breakage reduction, and manageability. This paper reports the activity of two shampoos and two conditioners which, enriched of zinc and chitin nanofibrils, are active both in vitro and in vivo in reducing hair flakes and sebum, ameliorating the hair shine and manageability.
