Definitions

• the present invention relates to the use of an agent comprising creatine, creatinine and / or their derivatives for hardening, improving gloss, strengthening and improving structure (restructuring) or for increasing the volume of keratin fibers, in particular damaged keratin fibers such as damaged human hair.
• Such influences are particularly noticeable on keratin fibers, especially on human hair, due to a lack of shine, reduced tear strength and poor combability. They are caused by aging processes that are primarily physiological or induced by physical (weathering), mechanical (combing, brushing) and chemical influences. With longer hair, these influences are particularly noticeable in the tips of the hair.

• the tensile strength of hair which is an indicator of the structural integrity of the hair cortex and thus a measure of the degree of damage, is determined by means of tension-elongation measurements customary for these purposes. 20 individual hairs are selected from each strand of hair and the individual hair diameters are determined using a computer-controlled laser micrometer. Subsequently, the force required to measure the force is measured using a tensile strain gauge (MTT 160/600 Series Miniature Tensile Tester, Serial No. 600.95.05.001, DIA-STRON Ltd., England). to tear individual hairs apart.

• bundle tensile strength (BZF) is determined from these individual tensile strength measured values, which differ from one another due to the different hair diameters, by calculating the tensile strength for a hair diameter of 0.08 mm (average diameter), taking into account the respective hair diameter.
• the hair density is finally converted into the unit of bundle tensile strength (cN / tex). The greater the numerical value of the bundle tensile strength, the less the hair damage.
• the difference between the mean values given above is statistically highly significant (significance level determined with the t-test: 99.9%).
• the bundle tensile strength is increased from 14.8 cN / tex to 15.5 cN / tex by the content of 1% by weight creatine; this corresponds to an increase of 4.7%.
• the combability of the hair is also an important parameter for describing the hair quality.
• Various external influences such as certain cosmetic treatments (bleaching, dyeing, perms), ventilation, frequent combing and brushing make the hair more difficult to comb, which is due to damage to the cuticle.
• the principle of most methods for measuring the combability is to measure the force (combing force) required to comb a comb through a strand of hair under precisely defined boundary conditions.
• Damaged hair (bleached) was treated with the shampoo according to Example 2 but without creatine (the amount of creatine was replaced by water): the combing power was 1.43 +/- 0.05 N (measured mean value from 3 strands of hair treated with shampoo) , Damaged hair (bleached) treated with shampoo according to Example 2 with 1% by weight creatine:
• the combing force was 1.21 +/- 0.08 N (measured average of 3 strands of hair treated with shampoo).
• the combing force is reduced by the content of 1% by weight creatine from 1.43 N to 1.21 N, that is to say by 15.3%.
• the addition of creatine thus results in a clearly detectable improvement in the combability of the hair.
• Tris (oligooxyethyl) alkyl ammonium phosphate 1.5% by weight
