DIY Hyaluronic Acid Hair Serum Recipe: Smooth & Silky

Are you tired of your hair feeling dry and lackluster? Looking for a natural solution to add shine and deep hydration without expensive salon treatments? Today, we're diving into the world of DIY hair care with a Hyaluronic Acid Hair Serum recipe. Hydrate, boost volume, and rejuvenate your locks for hair that feels soft, bouncy, and revitalized.

Why This Recipe Works

This dual-action bi-phase formula pairs deep aqueous hydration with lightweight botanical oils. Hyaluronic acid and provitamin B5 lock humectant moisture into the hair shaft, while polyquaternium 7 and hydrolysed wheat protein improve combability and detangling. Meanwhile, hemisqualane and argan oil seal the cuticle to smooth frizz and protect against breakage without weighing hair down.

Ingredients

Phase A (Water Phase)

32.1g Distilled Water

10g Hyaluronic Acid 1% Solution

0.5g Polyquaternium 7

0.25g Saliplus Liquid

1.5g Hydrolyzed Wheat Protein

0.5g D-Panthenol (Provitamin B5)

Phase B (Oil Phase)

2.5g Hemisqualane

2.5g Argan Oil

0.05g Lavender Essential Oil

0.1g Vitamin E Oil

Instructions

Phase A & Phase B Assembly

In a clean vessel, combine all water phase ingredients (distilled water, hyaluronic acid solution, polyquaternium 7, Saliplus liquid, hydrolyzed wheat protein, and D-panthenol).

Add the oil phase ingredients (hemisqualane, argan oil, lavender oil, and vitamin E) directly into the water phase mixture.

Packaging & Usage

Stir or shake well to combine all ingredients, then pour into a bottle fitted with a pump dispenser.

Because this formulation is bi-phase (unemulsified), the oil and water layers will separate naturally when resting.

Always shake vigorously before each use to blend the phases, pump into your palms, and smooth through damp or dry hair.

What Are the Key Ingredients in This Hair Serum?

Each active ingredient in this formulation targets specific hair hydration, repair, and styling needs:

Hyaluronic Acid: Acts as a powerful humectant, pulling hydration into dry hair fibers to boost elasticity and volume.

Hemisqualane: An ultra-lightweight plant-derived emollient that absorbs quickly, tames flyaways, and fortifies hair strands without greasy weight.

Argan Oil: Rich in fatty acids and antioxidants, it heals dry scalps, fights frizz, protects hair from environment damage, and adds brilliant shine.

Polyquaternium 7: A high-performance conditioning agent that smooths the hair shaft for easy detangling, combing, and brushing.

Hydrolyzed Wheat Protein: Penetrates the cortex to repair damage, increase hair body, and strengthen weak hair fibers.

D-Panthenol: Provitamin B5 that binds moisture, soothes the scalp, and adds lasting softness.

FAQs About This Hyaluronic Acid Hair Serum

Q: Why does my serum separate into two layers?
A: This recipe is intentionally bi-phase and does not contain an emulsifier. The top oil layer and bottom water layer naturally separate when standing; simply shake the bottle before dispensing.

Q: Why is a preservative necessary in this recipe?
A: Because Phase A contains distilled water and proteins, a broad-spectrum preservative like Saliplus Liquid is essential to prevent microbial growth and bacteria.

Q: What is the shelf life and storage for this product?
A: Stored in a cool, dry place out of direct sunlight, this serum has a shelf life of approximately 12 months.
