Yes. Here is what is in the bottle, and what the treatment does for your hair.
The product contains methylene glycol. When it is heated, methylene glycol releases some formaldehyde, and that is where the concern comes from. In 2023 the US Food and Drug Administration proposed a rule to ban formaldehyde and methylene glycol as ingredients in hair smoothing products.
The safety research points at two things: how much product is used, and how well the room is ventilated. In keratin smoothing, less is more, and I use less of it than most.

Ask me anything about it before we start. Text me a photo of your hair and I’ll tell you whether this is the right service and what it costs. The rest is on the Brazilian Blowout page.
