<p>There is provided a novel composition containing neem extract to repel and/or treat head lice in humans. The composition can be regularly applied to the hair and scalp of a human without being greasy and with its presence being generally understated by other humans. The composition broadly comprises a solution of azadirachtin including up to about 1 % of azadirachtin and the balance substantially all solvent suitable for permitting application of the solution to the human head. The solution may include at least 80 % of an alcoholic or spirit solvent, but non-alcoholic solvents may be used to provide a suitable vehicle to deliver the neem extract to the head preferably by means of spraying. The solvent must be able to dissolve the neem extract to produce a fine mist when sprayed and it must be acceptable to use on a human scalp.</p> |
