What the Brazilian Blowout Does
The Brazilian blowout is a salon treatment that uses a formaldehyde-releasing solution to coat the hair shaft. The solution is applied, then blow-dried and flat-ironed to seal it in. This process temporarily reduces frizz and adds smoothness by creating a thin layer around each strand.
Does the Brazilian Blowout Work
For most people, the treatment visibly reduces frizz and adds shine for several weeks. Results depend on hair type, condition, and aftercare. The straightening effect is temporary and gradually fades with washing. Very coarse or highly textured hair may see less dramatic smoothing than finer hair.
Key Considerations
The treatment can cause temporary dryness or breakage if not done correctly. Some formulas release small amounts of formaldehyde, which can irritate sensitive scalps. Always ask the stylist about the specific product used and ensure the salon is ventilated. For more details on the process and safety, see the American Academy of Dermatology at aad.org.
