There are millions of people that practice all kinds of beauty folklore theories and fables that get passed down through generations. Some of them are common sense and some simply are not true.
Many people think that rinsing out conditioner or a >hair treatment with cold water keeps the hair cuticle closed resulting in shiny hair. However, a cold-water rinse does not contribute to the closing of the hair cuticle. Controlling the correct pH balance by using a low pH level product will seal the hair cuticles leaving the hair shiny and silky. The pH level is a measurement of acidity or alkalinity in the hair that ranges from being either acidic (0-6.9) or alkaline (7.1-14). PH level is used as a scale to match our environment to our body and is essential when treating all hair conditions including frizzy hair. The pH balance of curly hair is the key to controlling unruly, frizzy dry hair. Healthy curly hair should have a pH balance of 4.5 – 5.5 making it slightly acidic. Therefore, the perfect hair conditioner should have a low pH level between 3.5 and 5 to restore the hair’s ideal balance resulting in healthy shiny curly hair.
The skin, which has blood vessels running throughout, is vulnerable to temperature change. Therefore, cold water rinsing will definitely have an effect on the scalp, but never on curly hair. So go ahead, turn up the temperature and enjoy your showers!
