5 . The hair-altering composition of claim 1 , wherein the composition is substantially free of ammonia and/or substantially free of MEA.
6 . The hair-altering composition of claim 1 further comprising a coloring agent, wherein the coloring agent comprises anion dyes, cation dyes, neutral dyes, or combinations of two or more thereof.
7 . The hair-altering composition of claim 1 further comprising one or more of:
an antioxidant,
a surface active agent,
an alcohol,
a skin conditioning agent and/or a fragrance,
a curl modifying agent,
a developer, or
water.
8 . The hair-altering composition claim 7 , wherein the antioxidant comprises ascorbic acid, sodium sulfite, sodium metabisulfite, sodium hydrosulfite, tocopherols, α-tocopherol, tocopheryl acetate, panthenol, selenium sulfide, zinc formosulfoxylate, isoascorbic acid, magnesium ascorbyl phosphate, ascorbyl glucoside, cysteine, thiourea, glyceryl monothioglycolate, thioglycerol, 2,5-dihydroxybenzoic acid, erythorbic acid, or combinations of two or more thereof.

19 . The hair-altering composition of claim 1 , wherein the hair-altering composition is one or more of:
a hair color altering composition,
a curl, kink, or hair texture altering composition, and
a disulfide bond breaking composition.
20 . The hair-altering composition of claim 19 , wherein hair treated with the composition exhibits a hair color altering ΔE of less than about 2.5 compared to a control composition having ammonia substituted for the 2-aminopropanol.
21 . The hair-altering composition of claim 20 , wherein the ΔE is measured after one or more color treatment cycles.
22 . (canceled)
23 . (canceled)
24 . A method for altering hair comprising:
applying the hair altering composition of claim 1 on a hair; and
rinsing the composition off of the hair with water to provide the altered hair,
optionally wherein the rinsing occurs at least about 10 minutes after the applying.
25 . (canceled)
26 . The method of claim 24 , wherein the composition is a color altering composition and the altered hair exhibits a hair color altering ΔE of less than about 2.5 compared to a hair treated with a control composition having ammonia substituted for the 2-aminopropanol.
27 . The method of claim 26 , wherein the ΔE is measured after applying and rinsing one or more times.
