What is Soda in hair salon? How does it work?
I’ll introduce one of our technical menu, “Soda” [Above shoulder S$15, below shoulder S$20] Our “Soda” is not just a soda.
The power of “Soda”, “charcoal”, “alum”

“CRONNA Cleansing Spa Shampoo Sumi” by Milbon, we are using in our salon, contains not only soda, but also charcoal and alum.
Good effect to hair and scalp
- it makes colour last longer by removing alkali
- Mild acidity takes care of scalp
- it cleanse dirtiness thoroughly by charcoal adsorption
Although there are lots of shampoo products, this soda shampoo has 6000ppm of carbonic acid. it helps improve blood circulation. In addition, it also contains “charcoal” which adsorb dirtiness. And “alum”, it is used for suppressing colour fading of food, is also has suppression effect for hair colour.
Suppression effect works much better on colour dyed on grey hair. hair colour looks even and nice right after colour. But it’s gradually fading, the part of white hair in particular. (it’s unfavorable shine…)
Combination of these three(soda, charcoal, alum) keep colour element inside hair and tighten hair cuticle. It makes colour last longer by doing it right after colouring. It’s good care when you dye your hair at salon.
