Name Ingredients:
Carbonic acid is a byproduct of cellular metabolism, which our bodies make every single day. When our cells take in carbon dioxide, that carbon dioxide mixes with an enzyme and water to form carbonic acid. Some companies use carbonic acid as an ingredient in their shampoos and claim that it can help to unclog sebum plugs in the scalp to restore hair growth for people with male pattern baldness.
Key insights:
- Carbonic acid is unstable and only lasts for seconds once it comes into contact with water before being broken down into hydrogen ions and bicarbonate, so it is unlikely that it would have any effect on scalp health.
- We do not recommend products that claim that carbonic acid can be used to treat any hair loss disorders, as there is just no evidence supporting this.
- Our experience tracking members: by itself, carbonic acid alone is not enough to improve hair loss outcomes.
