As result, hair fiber diameter, cross sectional area, elasticity and stiffness are all increased. The benefits are long term, surviving repeated rinsing and shampooing. These results are particularly beneficial in the treatment of fine hair. ## Claims ### Claim 1 A topically applied hair care composition having a pH from about 4.5 to about 5.5 comprising by weight: 0.5% to 20% of one or more reducing sugars having a molecular weight less than about 500 daltons; 1% to 80% of one or more proteins and/or amino acids obtained from soy, wheat, corn, rice, oat, quinoa, rapeseed, safflower, peanuts, almonds, sunflower, olives, alfalfa, clover, peas, beans, beets, lentils, lupins, Brazil nut, mesquite and carob; and 10%-70% of a cosmetically acceptable aqueous, alcoholic or aqueous-alcoholic base. ### Claim 2 (depends on 1) The composition of claim 1 further comprising 0.1% to 20% by weight of one or more glycosyl acceptors. ### Claim 3 (depends on 2) The composition of claim 2 wherein the glycosyl acceptor is lysine. ### Claim 4 (depends on 1) The composition of claim 1 further comprising 0.1% to 40% by weight of one or more alpha hydroxy acids, beta hydroxy acids, amino acids, tannins, hydrolyzed keratins, caffeine, carbohydrates or derivatives thereof, or amino sugars. ### Claim 5 (depends on 4) The composition of claim 4 comprising one or more of lactic acid, glycolic acid, malic acid, citric acid, tartaric acid, salicylic acid, alanine, arginine, aspartic acid, cysteine, glutamic acid, glycine, methionine, monosaccharides, disaccharides, N-acetylglucosamine, galactosamine, glucosamine or sialic acid. ### Claim 6 (depends on 1) A composition according to claim 1 wherein: the reducing sugar is of one or more of glyceraldehyde, arabinose, xylose, ribose, glucose, fructose, galactose, maltose, and lactose; and the proteins and/or amino acids are obtained from one or more of soy, wheat, corn, quinoa, Brazil nut or beets. ### Claim 7 (depends on 1) A composition according to claim 1 further comprising one or more of acetamide MEA, ammonium thioglycolate, allantoin, ascorbic acid, BHA, BHT, biotin, butylene glycol, butyl stearate, calcium chloride, calcium sulfate, cystine, caprylic/capric triglyceride, chitosan, cholesterol, cocamidopropyl betaine, collagen, cysteine, EDTA, elastin, glycerine, lactamide MEA, lanolin, lecithin (hydrolyzed), linoleic acid, linolenic acid, panthenol, pantothenic acid, pentetic acid, resorcinol, stearic acid, thioglycolic acid or urea. ### Claim 8 A method of treating hair comprising the steps of: providing a hair building composition having a pH from about 4.5 to about 5.5, comprising at least one ingredient that is able to covalently bond to the hair cortex, and at least one ingredient that is able to hydrogen bond to the hair cortex; applying the hair building composition to the hair; and letting the hair building composition dwell on the hair for about 5 to about 120 minutes. ### Claim 9 (depends on 8) The method according to claim 8 further comprising the steps of: providing a pre-treatment composition having a pH of about 7 to about 9; and applying the pre-treatment composition to the hair prior to applying the hair building composition. ### Claim 10 (depends on 8) The method of claim 8 further comprising the steps of: providing a post-treatment composition comprising: about 0.00001% to about 2% of polylysine by weight of the post-treatment composition; and about 0.5 to about 0 units of transglutaminase activity per gram of post-treatment composition; and applying the post treatment composition to the hair after the step of letting the hair building composition dwell on the hair. ### Claim 11 (depends on 9) The method of claim 9 further comprising the steps of: providing a post-treatment composition comprising: about 0.00001% to about 2% of polylysine by weight of the post-treatment composition; and about 0.5 to about 0 units of transglutaminase activity per gram of post-treatment composition; and applying the post treatment composition to the hair after the step of letting the hair building composition dwell on the hair. ### Claim 12 (depends on 8) The method of claim 8 wherein at least some of the hair being has a diameter of less than about 65μ prior to treatment.
