Abstract

A braided hair washing method includes washing braided hair using a washing agent that includes a microbubble washing composition and microbubbles, the microbubble washing composition including a protease and a lipase. The braided hair washing method can conveniently and effectively wash braided hair without collapsing the hairstyle.

Claims

1. A braided hair washing method that washes a person'"'"'s braided hair without changing a hairstyle, the method comprising washing the person'"'"'s braided hair using a washing agent that includes a microbubble washing composition, water, and microbubbles, which safely removes dirt, sebum, and old keratin adhering to surfaces of the person'"'"'s pores and hair without untwisting the braided hair, the microbubble washing composition including at least one alkali metal salt selected from the group consisting of alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal sulfates, alkali metal halides, and alkali metal salts of boron, a protease, and a lipase, and not including a surfactant;

removing the washing agent by rinsing the washing agent out of the braided hair with water; and

drying the braided hair using a drier such that the hairstyle before washing is maintained.

2. The method according to claim 1, wherein the microbubble washing composition includes the protease in an amount of 0.01 to 0.5 wt % based on the total amount of the microbubble washing composition, and includes the lipase in an amount of 0.1 to 1.0 wt % based on the total amount of the microbubble washing composition.

3. The method according to claim 1, wherein the microbubble washing composition includes the at least one alkali metal salt in an amount of 80 to 99.5 wt % based on the total amount of the microbubble washing composition.

4. The method according to claim 1, wherein the microbubble washing composition is used in an amount of 1 to 10 g per 6 to 10 liters of water.

5. The method according to claim 1, wherein the microbubble washing composition is used in an amount of 1 to 10 g per 6 to 10 liters of water and wherein the microbubble washing composition includes the at least one alkali metal salt in an amount of 80 to 99.5 wt % based on the total amount of the microbubble washing composition.

6. The method according to claim 5, wherein the alkali metal salt is an alkali metal carbonate.
