Examples

1. Formulations

The following formulations were prepared.

Medium (A)	(A)
		(3-aminopropyl) triethoxysilane	2.0g

Medium (A')	(A')
		Cocoamidopropyl betaine	1.5g
Citric acid	Adding to pH 3.5
		Lactic acid	---
Sulfuric acid	---
		Water (W)	To 98g

A ready-to-use pretreating agent (A) was prepared by mixing 2g of the agent (A) and 98g of the agent (A'). In the process, reagents (A) and (A') were shaken together for 3 minutes. The pretreatment agent (a) was then left to stand for about 5 minutes and then applied to the hair strand.

Medium (B)	(B)
		(3-aminopropyl) triethoxysilane	20.0g

Ready-to-use dye (B) was prepared by mixing 20g of reagent (B) and 80g of reagent (B'). In the process, reagents (B) and (B') were shaken together for 3 minutes. The dye (B) was then allowed to stand for about 5 minutes and then applied to the hair strand.

2. Coating of

The pre-treatment agent (a) and the coloring agent (B) were applied separately to the hair strand (Kerling 6-0) with a brush and were waited for their action for the specified time.

In example E1, the dye (B) was applied directly after washing off the pretreatment (A).

The tress is then first rinsed with water, then washed with shampoo and dried. Thereafter, the tress was visually evaluated.

These hair tresses were then washed several times with shampoo and again evaluated visually.

Strength: + not good + + moderate + + + excellent

In comparative example V1, no pretreatment was performed. In example E1, a hair strand was treated with a pretreatment (A).

The color intensity of E1 was further improved compared to V1.
