1. A method to improve softness of hair comprising:
a) providing an aerosol container containing an aerosol dry conditioner system comprising:
i) about 25% to about 70% liquefied propellant;
ii) about 0.1% to about 0.96% oleic acid;
iii) about 0.04% to about 0.42% glycerol monooleate;
iv) about 10 wt. % to about 75 wt. % non-aqueous volatile solvent,
wherein a weight ratio of oleic acid to glycerol monooleate is about 1:1 to about 2.5:1;
b) identifying a hair tip that is damaged due to loss of lipids, wherein the hair tip comprises a lipid layer;
c) applying the dry conditioner composition to the hair tip; and
d) allowing the dry conditioner composition to remain on the hair tip so the glycerol monooleate enhances penetration of the oleic acid into the hair tip and the oleic acid is incorporated into the lipid layer thereby replenishing the lipid layer and improving hair softness.
