TIGI Bed Head Straighten Out Anti-Frizz Serum — Sulfate-Free Smoothing Serum, 48-Hour Frizz Control and Shine

If you want salon-level smoothness without the fuss, this anti-frizz serum combines glycerin and conditioning polymers to hydrate strands, flatten the cuticle, and create a humidity-resistant barrier. The formula is designed for use on damp hair before blow-drying and heat-styling, delivering sleek, touchable results that won’t feel heavy or greasy.

How does Straighten Out reduce frizz and boost shine?

The serum tames flyaways by smoothing the hair’s surface and sealing moisture into each strand. Conditioning polymers form a thin protective layer that helps hair resist airborne humidity while glycerin attracts and retains hydration for glossy, healthy-looking finish.

• Smooths the cuticle to reduce texture and frizz
• Glycerin locks in moisture for lasting shine
• Polymers create a humidity barrier for up to 48 hours
• Non-greasy feel preserves movement and touchability

What’s the best way to use this serum in my styling routine?

Apply a small amount to towel-dried hair, working evenly from roots to ends, then blow-dry with a brush. For longer-lasting straightness, finish with a flat iron set around 200°C to seal the style and amplify shine.

• Use sparingly—start with a pea- to dime-sized amount for medium hair
• Distribute evenly to prevent weighed-down sections or residue
• Blow-dry thoroughly before flat-ironing for optimum hold
• Reapply a tiny amount to dry ends if you need mid-day smoothing

Will this serum work on my hair type and color-treated hair?

Straighten Out is formulated for all hair textures, from fine to coarse, and is sulfate-free, making it suitable for many color-treated and chemically processed hair routines. Because it’s lightweight, it won’t flatten fine hair when used correctly, and it helps protect treated hair from humidity-driven frizz.

• Safe for color-treated hair due to sulfate-free formulation
• Use lighter amounts on fine hair, more on thicker textures
• Helps manage waves, curls, and post-treatment frizz
• Works as part of a heat-styling protocol to lock in results

How long will the smoothing effect last and how often should I use it?

When applied and heat-sealed as directed, the serum supports smooth styles for up to 48 hours in typical conditions; results vary with humidity levels and activity. Use it every styling session on damp hair for consistent control, and refresh sparingly between washes if needed.

• Up to 48 hours of frizz resistance under normal conditions
• Daily application during styling delivers predictable results
• Touch up dry hair with a small amount for mid-day polish
• Increase protection in humid climates or after heavy sweating

Who is this for: Straighten Out is ideal for anyone who wants sleeker, shinier hair without heavy silicones or greasy buildup—perfect for people with frizz-prone, color-treated, or heat-styled hair who want salon-worthy smoothness at home. If you seek a lightweight, professional-grade serum that hydrates, protects against humidity, and helps you achieve long-lasting straight styles, this TIGI Bed Head product is built for your daily routine.
