why do some barbers wash hair with sparkling water?

Some barbers use sparkling water for its potential benefits in hair care. It's believed to help clarify hair by removing residue and product build-up, enhancing volume and texture. The carbonation in sparkling water can also provide a deeper clean compared to regular water, potentially leading to shinier, healthier-looking hair and scalp by balancing pH levels and reducing irritation from common scalp issues^[3][4].

However, not all experts agree on its effectiveness. Some professionals maintain that using club soda, akin to regular water, offers no significant advantages for hair^[2].
