Abstract

A method of conditioning human hair to provide a long lasting permanent hair wave includes the step of applying a reforming mixture to the hair after applying a wave solution but before applying a neutralizer solution. The reforming mixture includes magnesium sulfate, water and a hair reconstructor solution with a magnesium sulfate to reconstructor weight ratio within the range of from about 0.7 to 1 to about 2.7 to 1 and a water to reconstructor weight ratio within the range of from about 1 to 1 to about 3.5 to 1.

Claims

1. In a method of conditioning human hair to provide a long lasting permanent wave which includes the steps of applying a permanent wave solution to the hair to shape the hair followed by applying a neutralizer solution to the hair to neutralize the effect of the permanent wave solution and reconstitute the hair, the improvement comprising the steps of:

applying a reforming mixture to the hair after the hair has been shaped but prior to applying the neutralizer solution, said reforming mixture consisting essentially of magnesium sulfate, water and a reconstructor solution and having a magnesium sulfate to reconstructor weight ratio within the range of from about 0.7 to 1 to about 2.7 to 1 and a water to reconstructor weight ratio within the range of from about 1 to 1 to about 3.5 to 1; and

heating the hair for between about 15 to about 25 minutes after applying the reforming mixture but prior to applying the neutralizer solution.

2. The method of claim 1, including the further step of covering the hair with a plastic cap prior to heating.

3. The method of claim 1, wherein said reforming mixture is applied while the hair is wrapped and stretched on curling rods.

4. The method of claim 1, including the further step of warming the reforming mixture prior to applying said mixture to the hair.

5. In a method of conditioning human hair to provide a long lasting permanent wave which includes the steps of applying a permanent wave solution to the hair to shape the hair followed by applying a neutralizer solution to the hair to neutralize the effect of the permanent wave solution and reconstitute the hair, the improvement comprising the steps of:

applying a reforming mixture to the hair after the hair has been shaped but prior to applying the neutralizer solution, said reforming mixture consisting essentially of an aqueous solution of magnesium sulfate having between about 24% to about 42% by weight magnesium sulfate; and

heating the hair for between about 15 to about 25 minutes after applying the reforming mixture but prior to applying the neutralizer solution.

6. The method of claim 5, including the further step of covering the hair with a plastic cap prior to heating.

7. The method of claim 5, wherein said reforming mixture is applied while the hair is wrapped and stretched on curling rods.

8. The method of claim 5, including the further step of warming the reforming mixture prior to applying said mixture to the hair.
