A lightweight, leave-in smoothing serum built on QT Charge Technology™ — Bare Anatomy's proprietary carbohydrate complex that binds moisture directly to the hair shaft for lasting frizz control and 37% smoother hair, rather than just coating the surface.

The formula pairs QT Charge Technology™ (Xylitylglucoside, Anhydroxylitol, Maltitol, Xylitol, Saccharide Isomerate) with Omega 3, 6 & 9 from Flaxseed and Safflower Oils to repair weak strands, smooth the cuticle, and protect against UV and heat damage. Phytosqualane — a plant-derived sebum analog — hydrates the hair shaft and improves elasticity without greasiness. Niacinamide restores hair texture and smooths rough ends. A silicone complex (Dimethicone + Phenyl Trimethicone + Cyclopentasiloxane) seals the cuticle for mirror-like shine and heat protection.

Sulphate-free, paraben-free, and vegan. Dermatologically tested and suitable for all hair types — straight, wavy, and curly. Apply a few drops to damp or dry hair, concentrate on mid-lengths to ends, and style as usual. No rinsing required.

  1. Shampoo and condition as usual, then towel-dry hair until damp (not dripping wet).
  2. Dispense 2–3 drops onto your palm — use up to 4–5 drops for very thick or long hair.
  3. Work through mid-lengths to ends — distribute evenly through the areas most prone to frizz, dryness, or roughness. Avoid the roots.
  4. Style as desired — blow-dry, diffuse, air-dry, or straighten. No rinsing needed. The serum protects against heat damage as you style.
  5. For dry hair: apply 1–2 drops to smooth flyaways and add shine between washes — works as a frizz-control refresher any time of day.

For external use on hair only. Contains Perfume — patch test before use if you have a known fragrance sensitivity. Individual results may vary by hair type and condition.

Most hair serums rely on a single silicone to coat the surface — which smooths hair briefly but wears off in humidity and leaves behind greasiness or buildup over time. This serum is built around a fundamentally different mechanism.

  • QT Charge Technology™ — binds moisture to the hair shaft from within for 37% smoother hair that holds in humidity, not just in the mirror
  • Omega 3, 6 & 9 — repairs the hair's lipid layer, strengthens weak strands, and provides UVA/UVB protection against sun-related dryness
  • Phytosqualane — mimics hair's natural sebum for hydration and elasticity without heaviness or buildup
  • Niacinamide — restores hair texture and smooths rough cuticles from within
  • Silicone cuticle seal — Dimethicone + Phenyl Trimethicone deliver lasting shine and heat protection without a greasy finish
  • Sulphate-free, paraben-free, vegan — dermatologically tested for all hair types

    QT Charge Technology™

    Moisture Binding + Smooth

    A proprietary carbohydrate complex — Xylitylglucoside, Anhydroxylitol, Maltitol, Xylitol, and Saccharide Isomerate — that binds to the hair shaft and locks in moisture from within, rather than coating the surface. The result is a lasting smoothness and frizz reduction that holds even in humidity, improving measured smoothness by 37%.

    A complete essential fatty acid profile delivered via Flaxseed (Linum Usitatissimum) Oil and Safflower (Carthamus Tinctorius) Oil. Omega fatty acids repair the hair's lipid layer, add natural weight to weak and limp strands, smooth the cuticle from root to tip, and protect against the UVA/UVB sun exposure that accelerates hair dryness and breakage.

    Phytosqualane

    Hydrate + Elasticity

    A plant-derived analog of the natural oil (squalane) found in healthy hair's sebum layer. Phytosqualane hydrates the hair shaft, improves elasticity and bounce, and delivers a silk-like finish without the greasiness or heaviness of heavier oils — suitable even for fine and low-porosity hair.

    shield

    Niacinamide + Silicone Shield

    Restore + Protect

    Niacinamide (Vitamin B3) improves overall hair health by smoothing rough ends and restoring hair texture from within. Dimethicone, Phenyl Trimethicone, and Cyclopentasiloxane then seal the cuticle with a weightless protective layer — delivering high-gloss shine, heat protection, and lasting frizz resistance without buildup.

    Why QT Charge Technology™ Wins

    Moisture Bound In, Not Sitting On Top

    An ordinary serum coats the surface and wears off. QT Charge Technology™ binds moisture to the hair shaft from within — so the smoothness lasts through washing, heat styling, and humidity rather than disappearing by midday.

    Got Questions? We've Got Answers.

    Everything you need to know about the Bare Anatomy Ultra Smoothing Hair Serum.

    What does this serum actually do and how is it different? +
    It's a lightweight leave-in hair serum built on QT Charge Technology™ — a carbohydrate complex that binds moisture directly to the hair shaft rather than just coating the surface. This means frizz reduction that holds through heat, humidity, and washing rather than wearing off by midday. Omega 3, 6 & 9 (from Flaxseed and Safflower Oil) repair the hair's lipid layer and add weight to weak strands. Phytosqualane hydrates and improves elasticity. Niacinamide restores hair texture. A silicone complex (Dimethicone + Phenyl Trimethicone) seals the cuticle for lasting shine and heat protection. Clinical result: 37% improvement in hair smoothness.
    How do I use it — damp or dry hair? +
    Both. For best results, apply a few drops to towel-dried (damp) hair after shampooing — distribute through mid-lengths and ends and style as usual. You can also apply to dry hair as a frizz-control and shine refresher between washes. Avoid the roots to prevent weighing down. No rinsing required — leave it in and style as desired.
    Is it suitable for fine hair? Will it weigh hair down? +
    The formula is designed to be lightweight and non-greasy — suitable for all hair types including fine, thin, and low-porosity hair. The key is using a few drops and focusing on mid-lengths to ends. Phytosqualane and the volatile silicone (Cyclopentasiloxane) evaporate cleanly without leaving a heavy residue, while Dimethicone provides lasting smoothness without buildup at the amounts used in this formula. Users with wavy and curly hair also report excellent frizz control and polish without loss of natural texture or movement.
    What is QT Charge Technology™ and does it actually work? +
    QT Charge Technology™ is Bare Anatomy's proprietary carbohydrate complex — Xylitylglucoside, Anhydroxylitol, Maltitol, Xylitol, and Saccharide Isomerate — that works by binding to the hair shaft and increasing moisture retention from within rather than simply coating the surface. In clinical testing, this technology was shown to improve hair smoothness and texture by 37% with regular use. The result is lasting frizz control that holds in humidity, rather than the temporary smoothing effect of standard silicone-only serums.
    Does it protect hair from heat styling? +
    Yes. The silicone complex (Dimethicone + Phenyl Trimethicone + Cyclopentasiloxane) forms a protective layer around each strand before you apply heat — reducing the direct damage from blow-dryers, straighteners, and curling irons. Additionally, Omega 9 in the Flaxseed and Safflower Oils provides UVA/UVB protection against sun-related dryness and color fading when worn outdoors.
    What's in it — and what's it free from? +
    Key actives: QT Charge Technology™ (Xylitylglucoside, Anhydroxylitol, Maltitol, Xylitol, Saccharide Isomerate), Omega 3, 6 & 9 (Flaxseed Oil + Safflower Oil), Phytosqualane, Niacinamide, Tocopheryl Acetate (Vitamin E), Shea Butter, Pelvetia Canaliculata (Seaweed) Extract, and a silicone complex (Dimethicone + Phenyl Trimethicone + Cyclopentasiloxane). Free from sulphates, parabens. Vegan formula. Dermatologically tested. Suitable for all hair types.

    Best For: Dry, frizzy, damaged, rough, or unmanageable hair — all hair types including straight, wavy, and curly. Especially effective for hair that is prone to humidity frizz, heat damage, or looks dull and lacks shine.

    Use Tip: 2–3 drops is enough for most hair lengths. For very thick or long hair, use up to 4–5 drops. Concentrate on mid-lengths and ends — avoid the roots to prevent any heaviness near the scalp.

    Pairs Well With: The Bare Anatomy Ultra Smoothing Shampoo and Conditioner (use as Step 1 and 2 before this serum for the complete smoothing ritual).

    Why This Serum Stands Out

    "
    Most hair serums pick one mechanism and stop there — a silicone coat for shine, or a heavy oil for moisture, or a heat shield that disappears by noon. This one refuses that trade-off. QT Charge Technology™ binds moisture to the shaft from within so the smoothness actually holds. Omega 3, 6 and 9 repair the lipid layer that dryness and heat styling strip away. Phytosqualane mimics the hair's own sebum for elasticity that doesn't weigh anything down. Niacinamide restores texture. And the silicone complex seals it all in with a cuticle shield that reflects light like glass. Sulphate-free. Paraben-free. Tested on all hair types. One formula — smooth, shiny, strong hair from the very first drop.
