TLDR Review: IGK GOOD BEHAVIOR Smoothing Spray
Verdict
The IGK GOOD BEHAVIOR Spirulina Protein Smoothing Spray is highly effective at taming frizz, boosting shine, and providing heat protection—especially in humid conditions. However, the very strong scent and aerosol fumes might be a dealbreaker for sensitive users or those who prefer a more subtle product. If you’re okay with managing the fragrance and applying carefully, it’s a solid choice for sleek, manageable hair. For a fragrance-free option with easier application and no inhalation concerns, consider alternatives like the Oribe Royal Defiance Strength & Moisture Spray.
