Many foreigners living in Korea complain about the drying and damaging effects of the hard and very chlorinated water on their hair and skin. My hair's been shedding more than usual and my scalp is very dry and sensitive and after trying several shampoos (ranging from grocery store brands to high-end salon shampoos that cost me a fortune to import) I was at my wits end, until I tried the following rinse that's been circulating around the web:
Bicarbonate of Soda (aka baking soda)
Lemon or Apple Cider Vinegar (for dark hair)
White Vinegar (for blonde hair)
Clarifying or chelating shampoo
Use a small plastic bowl and mix 3 teaspoons of shampoo (I use Joico K-PAK Chelating Shampoo) and about 4-5 teaspoons of bicarbonate of soda before getting into the shower. If you have long or very thick hair, you can double the mixture.
When you're in the shower, wet your hair and lather the bicarbonate of soda mix from root to tip. Leave in for about 5 mins. then rinse thoroughly. Next, add about 30ml (1 oz) of vinegar and a few drops of lemon juice to 500ml (17 oz) bottled water and pour it over your hair making sure it covers all the hair. (TIP 1: Tilt head back and close your eyes as it can sting quite a bit! TIP 2: You can add a few drops of tea tree oil to this rinse- it has many good therapeutic properties.) Vinegar is great for your hair: it balances the hair and scalp pH, closes hair cuticles and helps alleviate dry scalp, dandruff, hair loss and removes build-up! If you have oily hair, don't bother with a conditioner as the vinegar will make your hair nice and soft, but if you have very dry hair you can use a light conditioner on the ends. Lastly, dry hair with a hairdryer. The vinegar smell will disappear as soon as your hair is dry.
This really made my hair feel light, bouncy and super shiny. I wouldn't recommend doing this too often though, as it can dry out your hair. Once a week or every other week should be fine!
