Method For Increasing Hair Growth

Abstract

The present invention provides a method for stimulating hair growth, which comprises applying a composition containing at least one energy-inducing compound selected from the group consisting of 5′-AMP and ATP. Such a composition is particularly effective in increasing the DNA synthesis in dermal papilla cells.

1 . A method for stimulating hair growth which comprises applying to hair or scalp a composition comprising at least one energy-inducing compound selected from the group consisting of 5′-AMP and ATP. 
   
   
       2 . The method of  claim 1  in which the energy-inducing compound is present in an amount ranging from about 0.0001% to 10% by total weight of the composition. 
   
   
       3 . The method of  claim 1  wherein the composition comprises 5′-AMP in an amount ranging from about 0.25 mM to about 1 mM. 
   
   
       4 . The method of  claim 1  wherein the composition comprises ATP in an amount ranging from about 0.25 mM to about 0.5 in M. 
   
   
       5 . A method for increasing the DNA synthesis of dermal papilla cells in hair follicles which comprises applying to the dermal papilla cells a composition comprising at least one energy-inducing compound selected from the group consisting of 5′-AMP and ATP. 
   
   
       6 . The method of  claim 5  in which the energy-inducing compound is present in an amount ranging from about 0.0001% to 10% by total weight of the composition. 
   
   
       7 . The method of  claim 5  wherein the composition comprises 5′-AMP in an amount ranging from about 0.25 mM to about 1 mM. 
   
   
       8 . The method of  claim 5  wherein the composition comprises ATP in an amount ranging from about 0.25 mM to about 0.5 mM. 
   
   
       9 . A topical composition for application to hair or scalp to stimulate hair growth comprising at least one energy-inducing compound selected from the group consisting of 5′-AMP and ATP. 
   
   
       10 . The topical composition of  claim 9  in which the energy-inducing compound is present in an amount ranging from about 0.0001% to 10% by total weight of the composition. 
   
   
       11 . The topical composition of  claim 9 , which comprises 5′-AMP in an amount ranging from about 0.25 mM to about 1 mM. 
   
   
       12 . The topical composition of  claim 9 , which comprises ATP in an amount ranging from about 0.25 mM to about 0.5 mM.
