TIGI Bed Head Straighten Out anti-frizz serum — Sulfate-free smoothing serum, 48hr shine & humidity protection

If you want sleek, touchable hair without heavy residue or constant battling with humidity, this salon‑grade serum is formulated to lock moisture into each strand, tame flyaways, and create a protective barrier against frizz. Lightweight glycerin and conditioning polymers smooth the cuticle and boost shine while letting hair move freely. Designed for use at home or in professional settings, Straighten Out works best when applied to damp hair before blow‑drying and heat‑styling.

How does Straighten Out reduce frizz and protect styles?

The formula combines humectants and polymers that help seal the hair surface and repel moisture spikes from the air. That barrier smooths the cuticle, minimizing friction and the puffing that causes frizz, so styles stay sleeker for longer.

• Glycerin attracts and locks in moisture for balanced hydration.
• Conditioning polymers form a lightweight shield against humidity.
• Sulfate‑free base avoids stripping natural oils that help maintain smoothness.

When and how should I use the serum for best results?

Apply a small amount to towel‑dried hair, working from mid‑lengths to ends and lightly through roots if needed. Blow‑dry with a brush for a sleek foundation, then finish with a flat iron (around 200°C) to set a long‑lasting straight look.

• Work into damp hair for even distribution and easier styling.
• Blow‑dry with tension to enhance straightening before heat‑sealing.
• Use sparingly on fine hair to avoid buildup; add more for thick or coarse textures.

Will this serum weigh my hair down or leave it greasy?

Straighten Out is formulated to be lightweight and non‑oily, providing shine without heaviness. It moisturizes without coating strands in residue, so hair remains bouncy and touchable rather than limp.

• Light texture suitable for all hair types—adjust dose by hair density.
• Rinse‑free styling aid that won’t replace your conditioner or mask.
• Leaves a glossy finish while preserving natural movement.

How long will the smoothing effect last and does humidity affect it?

The product is designed to help styles resist humidity for up to 48 hours when used with heat styling. Environmental humidity can still challenge any style, but the serum’s barrier technology reduces hair swelling and frizz during humid conditions.

• Best longevity when combined with proper blow‑drying and flat‑ironing.
• Ideal for travel or busy days when you need longer‑lasting control.
• Reapply lightly to dry hair for targeted touch‑ups if needed.

Who is this for: Straighten Out is ideal for anyone seeking salon‑level smoothness at home—people with naturally frizzy, wavy, or unruly hair who want a sleeker finish, as well as those who frequently heat‑style and need humidity protection. Because the formula is lightweight and sulfate‑free, it suits a wide range of hair textures and routines; simply tailor the amount used to your hair’s thickness and desired shine level.
