  • Administration of agents inducing DOPAchrome tautomerase (TRP-2) expression for protecting hair follicle melanocytes
    Publication number: 20050208086
    Abstract: Agents inducing the expression of DOPAchrome tautomerase 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.
    Type: Application
    Filed: December 13, 2004
    Publication date: September 22, 2005
    Inventors: Stephane Commo, Bruno Bernard
  • Administration of agents mimicking dopachrome tautomerase (TRP-2) activity for protecting hair follicle melanocytes
    Publication number: 20050186233
    Abstract: 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.

  • Screening of candidates for biological hair care activity
    Patent number: 6113889
    Abstract: 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.
    Type: Grant
    Filed: January 20, 1999
    Date of Patent: September 5, 2000
    Assignee: Societe l'Oreal S.A.
    Inventors: Fran.cedilla.oise Jarrousse, Stephane Commo, Olivier Gaillard, Bruno Bernard
