Hi Gorgeous Hair Enthusiasts!

Why We Guarantee 100% Human Hair (And How You Can Tell!)
We understand trust is everything, especially when buying online. Here’s how we ensure authenticity and how you can verify it:
- Ethical Sourcing: We partner directly with trusted suppliers known for ethical practices, sourcing only the finest Remy human hair. This means the cuticles are intact and aligned in the same direction, preventing tangling and mimicking natural hair flow.
- The Feel Test: Genuine human hair feels incredibly soft, smooth, and natural to the touch. Synthetics often feel unnaturally smooth, coarse, or plasticky. Run your fingers through it – the difference is undeniable.
- The Burn Test (Use Caution!): This is the ultimate test. Take one single strand and carefully burn the end:
- Human Hair: Burns slowly, turns to ash, smells like burning hair or protein (similar to fingernails), and self-extinguishes.
- Synthetic Hair: Melts quickly, forms a hard plastic bead, smells like chemicals or burning plastic, and may continue to melt.
- Water Absorption: Real hair absorbs water readily. When wet, it feels saturated and becomes heavier. Synthetic hair often repels water, staying lighter and feeling less saturated.
- Styling Versatility: True human hair can be heat-styled (curled, straightened), colored (within reason, consult a pro!), and treated just like your bio hair. Synthetics melt under high heat and are difficult to dye effectively.


The Post-Wash Curl: It’s Science, Not a Flaw!
So, you’ve lovingly washed your new extensions, followed the care instructions, and now they have a gentle wave or curl you didn’t expect? This is completely normal for high-quality, 100% human hair! Here’s the science behind it:
- The Protein Structure: Hair is primarily made of keratin protein. This protein structure contains natural bonds (hydrogen bonds and salt bonds) that give your hair its shape – straight, wavy, or curly.
- Water’s Power: When you wash your hair extensions, water molecules penetrate the hair shaft. This disrupts the hydrogen bonds temporarily.
- Drying & Reformation: As the hair dries, these hydrogen bonds reform. However, they don’t always snap back into their exact original configuration. If the hair dries while gathered (like in a ponytail during washing) or laying in a certain way, these bonds can reform in a slightly different pattern, creating a new wave or curl. It’s essentially the hair “remembering” the shape it was in while wet.
- Natural Variation: Remember, human hair comes from diverse donors. Even hair labeled “straight” naturally possesses subtle variations in its protein structure. Washing can sometimes reveal or enhance these inherent, very slight textures.

Don’t Fret! Your Action Plan for Post-Wash Waves/Curls
Seeing a curl doesn’t mean your extensions are damaged or fake! It means they’re genuinely human and reacting naturally. Here’s exactly what to do:
- Gentle Detangling (Wet): After washing, while hair is still very damp, use a wide-tooth comb or a special loop brush designed for extensions. Start from the ends and work your way up slowly to the bonds/wefts. Never tug on wet hair.
- Smoothing Leave-In: Apply a lightweight, silicone-free leave-in conditioner or detangling spray. This helps smooth the cuticle and provides slip for styling.
- Controlled Drying is KEY: This is the most crucial step to prevent unwanted texture!
- Air Drying: If air drying, gently comb through once more after applying leave-in. Carefully lay the hair extensions flat on a clean towel or hang them to dry completely straight. Avoid bunching them up. You can loosely braid or wrap them around your hand for a controlled wave if desired, but for straight results, keep them smooth and straight while drying.
- Blow Drying (Best for Straight Results): For guaranteed straightness, blow-drying is recommended. Use a heat protectant spray! Section the hair. Using a paddle brush or a vent brush, tension-dry each section, directing the airflow down the hair shaft from roots to ends. Keep the dryer nozzle moving and use medium heat, not high. Ensure the hair is completely dry.
- Flat Ironing (If Needed): Once the hair is 100% dry, if any slight waves remain, you can use a flat iron. Always use a heat protectant! Set the iron to a medium heat setting (around 300-350°F / 150-180°C is usually safe for quality human hair). Glide the iron smoothly down each section. Don’t hold it in one spot. One pass is often enough.
- Avoid Over-Washing: Wash your extensions only when necessary (typically every 15-20 wears, or when product buildup occurs). Frequent washing increases the chance of the bonds reforming in a waved pattern.
Pro Tip: Sleeping on a silk or satin pillowcase helps maintain smoothness and reduces friction, minimizing any potential for waves to develop overnight.
