摘要:
Agents mimicking DOPAchrome tautomerase activity are administered, notably topically applied, to protect and/or regenerate the melanocytes of hair follicles, to promote the cyclic renewal of the follicular pigmentation unit, to prevent and/or limit and/or arrest the development of canities, and to maintain the natural pigmentation of gray or white head hair and/or body hair.

摘要:
The present invention concerns the use of a polypeptide comprising a sequence having at least 90% identity with all or part of BNIPXLβ, for cosmetic or therapeutic applications, in the treatment or prevention of premature canities in humans, said portion comprising at least 30 amino acids, as well as the use, for the same purpose, of a molecule comprising a RNAi sequence having at least 90% identity with all or part of the cDNA sequence of BNIPXLβ, said part comprising at least 18 nucleotides.The invention also concerns methods for screening molecules modulating the expression of a gene coding for BNIPXL-beta and molecules modulating the activity of the BNIPXL-beta polypeptide, in order to identify an agent for use for cosmetic or therapeutic purposes in the field of pigmentation. The invention also encompasses various uses of molecules which may be identified by these methods.

摘要:
The invention concerns a procedure for testing a potentially-active substance used in the hair-care field, this procedure being characterized by the fact that a fragment of at least one hair follicle without dermal papilla is isolated, this fragment being taken from beneath the point of attachment of the sebaceous gland and excluding the portion of the hair shaft located above the point of attachment of the sebaceous gland; that this fragment is incubated in a suitable culture medium for a sufficient period; that this fragment is placed in contact with a potentially-active hair-care substance; that a marker of the activity of said tested substance is quantitatively determined; and that the results of this determination are assessed as they compare to a control.

摘要:
At least one compound selected from among coumarin and/or derivative thereof, butylated hydroxyanisole, ethoxyquine and mixtures thereof, and admixtures thereof with other active agents selected from among active agents for combating desquamative conditions of the scalp, plant extracts having propigmenting activity and active agents that slow hair loss and/or promote hair regrowth, are useful for preventing and/or limiting and/or stopping the development of canities.
