Clip-Ins Washing Guidelines
Curly extensions are designed to be styled after washing to achieve your perfect blend.
• Wash after 10–15 wears (or when product buildup occurs)
• Always detangle gently before washing
• Use lukewarm water
• Cleanse with a sulfate-free, curl-safe shampoo
• Apply conditioner mid-shaft to ends (avoid clips & bands)
• Rinse thoroughly and gently squeeze out excess water
• Do not rub, twist, or wring
Pro Tip: Over-washing reduces longevity. Less is more.
Drying
- Pat dry with a microfiber towel
- Air dry flat for best curl integrity
- Optional: Diffuse on low heat + low airflow
- Allow curls to fully dry before storing.
Detangling
• Always detangle from ends upward
• Use fingers or a wide-tooth comb
• Detangle when wet or with a light leave-in spray
• Avoid heavy oils that cause buildup
→ Gentle handling preserves the curl pattern and cuticle alignment.
Styling
Curly extensions are designed to be styled after washing to achieve your perfect blend. Techniques like finger coiling, separating curls, or light heat styling can help match your exact pattern.
- Try finger coiling smaller sections to match tighter curls
- Finger coil larger sections to match 3A curls
- Gently separate curls for a looser pattern
- Use a curling wand on select pieces for precision blending
- Apply a light cream, leave-in or mousse + diffuse to redefine curls
- Safe to heat style up to 350°F (use heat protectant)
- For curl refresh: lightly mist with water + leave in conditioner
- Keep extensions tangle-free + for our favorite moisturizing products, click here.
→ Remember, the more heat and color processing, the shorter the lifespan.
Storage
• Store fully dry
• Keep in a satin bag, box or hanger
• Lay flat or loosely coiled
• Keep away from humidity
→ Proper storage prevents tangling and preserves texture.

Perfect blend
"Curls matched effortlessly and the Seamless was virtually unrecognizable. Best clip in I’ve ever purchased and worth it. When washed, the curls go right back to its natural pattern just as normal. The smell fresh out the pack was amazing and you can tell care is given through packaging. Will definitely be ordering more"
I was quite pleased with
"I was quite pleased with the hair quality and the packaging :)"
Yes!
"This hair is amazing and blends so well with my 3b-3c hair. The seamless clip ins are practically invisible especially in the crown area. I feel like myself because this hair mimics my natural curly hair so well. I ordered the 22 inch and I am very satisfied with this length. I am a customer for life. Thank-you for blessing us curly girls with the perfect extensions."
I love themmm I bought
"I love themmm I bought 2 sets one of the Sambi and the wavy curly will definitely purchase more get them quick ladies they sell out super fast 😫💗"
Amazing quality hair!
"The hair quality is amazing. The hair is so soft and shiny. I like that I can blend the extensions well with my hair. I originally bought the Sambi extensions but the curl was curlier than my hair so I exchanged for the wavy curly and it matched better. I was a little frustrated with how long it took to receive a response when I emailed about exchanging. After that it took over two weeks to recieve the new extensions. It took about a month to receive my extensions which was a little frustrating. Aside from that, I am very happy with my purchase. Well worth the money! 😊"
I could have chose a texture closer to mine
"The hair is beautiful and looks so amazing in my head. But I wish there was a bit more accurate representation to the curl pattern. I have 3c hair and I thought the Sambi was going to work because it seemed to look a bit coily. But when I got my hair it was only coily at the ends and wavy throughout the rest of the hair. It might have been because of the length of the hair, weight down the curls. But either way the package is dope, the hair is nice."
Soft and pretty
"I’m very happy with my purchase of the Seamless Sambi off black clip ins. The curls are so soft yet still textured enough to blend in with my hair. The only problem is the color. My bundle was darker then off black. I had to do a bleach wash and try to tint the clip in extensions to match my natural, off black hair. I also ordered the off black 1 clip Sambi ponytail around the same time and when I compared the two, fresh out of the pack, the colors were totally different. That’s only a minor issue, though. I also love the thin, seamless tracks. That is so genius and innovative! Customer service is always wonderful. This is my third purchase from Curly Heaven and the products are amazing. I receive a lot of compliments because the pieces are so well made and versatile, you can easily create a salon quality style at home."
I loved them! 🤩 I will definitely ask again. Thank you.

Amazing!
"This is my third time buying from curly hair heaven. I originally bought the 18" wavy hair regular and 18" seamless wavy because I was transitioning with my curls and than bought the 18" Sambi when they were getting back to my old curls! Both were amazing, soft hair, perfect color, was able to wash them and they bounced right back. The hangers they have on here hold them perfectly. Customer service is amazing, they even sent a mask with the order! So cute and thoughtful. My only advice would be if you have thinner hair definitely get the seamless extensions! The original is a bit heavy and would work perfect with thicker hair. I over estimated the thickness of my hair (wishfully thinking) and the seamless was great and you couldn't see them at all! To blend, watch their tutorials! Helps a ton."
