- Curly - Falls shortest (most volume)
Your hair may include 1-2" extra length since our Remy hair has natural ends. Trim to your perfect length or leave natural.

Product Information
Good to Know
Our extensions are Ratio 2 - a density between single drawn and double drawn. This means beautiful fullness at the top with naturally tapered ends that blend seamlessly with your own hair.
Colors may appear slightly different depending on your screen. Need help matching? Contact us for a free consultation.
Our straight hair has a natural, subtle body wave and may wave slightly after washing. This is characteristic of real human hair - not a defect. For a sleeker finish, simply flat iron after styling.

Want to keep your Perfect Locks' clip-in hair extensions looking their best? Follow these easy steps:
-
Brush your extensions thoroughly with Perfect Locks' specially designed detangling brush before and after each use to remove tangles and knots.
-
Style with low to medium heat and protect your hair with a heat protectant spray.
-
Keep your extensions hydrated with Perfect Locks' mild shampoo and conditioner, and let them air dry for best results.
-
Proper storage is key for preventing tangling and matting. Keep your extensions in top shape by storing them flat, in the included Perfect Locks' satin storage pouch, or hanging them.
-
Avoid using hair spray or gel on your extensions as this can cause build-up and damage. Wash and condition them every 2 to 3 weeks or as needed with Perfect Locks' specially formulated hair care products.
-
Keep your extensions looking their best by avoiding sleeping with them in and being careful when swimming and playing active sports.
-
Finally, regularly check the clips and make sure they are secure to ensure your Perfect Locks' extensions stay in place.
By following these simple steps, you'll be able to enjoy beautiful and healthy clip-in hair extensions that last for months to come with Perfect Locks!
1. Section the Hair 2 min
Part your hair horizontally at the nape and clip everything above it out of the way. This bottom section is the base for your widest weft.
2. Tease and Prep the Roots 1 min
Lightly backcomb the roots of the section so the clips have something to grip. A little dry shampoo or hairspray adds texture and stops the wefts sliding.
3. Attach the First Weft 2 min
Take the widest weft and press it against the teased roots. Snap the middle clip first, then the sides, so it sits flat and even across your head.
4. Layer Additional Wefts 5 min
Work upward in sections about an inch apart, using narrower wefts toward the sides. Keep every weft below the temple line so nothing peeks through.
5. Blend and Style 3 min
Let your own hair down over the wefts and brush the two together. Style as normal, and keep heat low to protect the extensions.
Seamless clip-ins are more lightweight than lace clip-ins and suited best for those with thinner hair, or those who wear extensions less frequently. They are typically made with a clear or skin-colored band that blends in with your own hair, making them virtually invisible. They are easy to apply, remove and they do not require any professional help. They are also less damaging to the natural hair as they don't require any heat or glue.
Blending clip-in extensions with your own hair is a great way to achieve a fuller and more voluminous look without the commitment of permanent extensions. But before you can blend them seamlessly with your own locks, there are a few key steps to take. Brush your hair thoroughly to remove any tangles or knots. Part your hair where you want to pseamless the clip-ins. Take a small section of your own hair, about the same width as the extension, and clip the extension to it. Repeat this process until you have added all of the extensions that you want to use. Use a comb or brush to blend your own hair with the extensions. Style your hair as desired.
When it comes to washing your clip-in hair extensions, it's all about striking the perfect balance between keeping them clean and maintaining their longevity. While it may be tempting to wash them after every use, it's important to remember that over-washing can cause damage and shorten the lifespan of your extensions. A general rule of thumb is to wash your clip-ins every 6-8 weeks, or as needed. This means that if you're using them frequently, you may need to wash them more often. But if you're using them less, you can stretch the time between washes.
We typically don't recommend sleeping with any type of clip-ins, as they can be easily removed. However, if you must, just make sure to tie your extension and natural hair into a loose braid before bedtime – this will help prevent tangling while you sleep. Additionally, keep any clips facing up so they won’t get caught on your pillowcase while you’re tossing and turning during the night.
One of the biggest perks of seamless clip-ins is their virtually undetectable nature, making them perfect for those with fine or thin hair. Unlike traditional clip-ins that can often have visible clips, seamless clip-ins have an invisible band or clear clips that blend seamlessly with your natural hair, leaving you with a look that is almost impossible to spot. Seamless clip-ins are designed to be lightweight and easy to apply, which makes them comfortable to wear for long periods of time. Not only that, but they also cause less stress on your natural hair and are less likely to damage it. So you can feel confident and beautiful while also taking care of your natural hair.

I was recently gifted these extensions but will be buyer more from them. I’ve tried countless brands and these bag far are the best I have tried
Amazing hair. Looked flawless. Couldn’t even tell I had clip ons.
I am blown away by the quality of these extensions. I love how flat the clip-ons are, very easy to put on and they blend perfectly with my hair. My husband couldnt even tell what was my hair and what was extensions. They look so natural! Definitely would recommend! Worth the price!

They’re so easy for me to put in. They do not feel heavy at all. I love this color , it blends the best with my hair. This is my third set of extensions from perfect locks . I love the seamless but I also have the original and they’re really lightweight on my head . It’s just quality hair every time so it works no matter what . It’s beautiful ! They last longer than any I’ve purchased elsewhere. I think it’s been a year on my first set and they still look 👌

I've used several types of hair extensions and this hair is the best! These clip ins are not noticeable and comfortable. Will be buying more different colors for highlighted effects in future.
Dear Pearl, Thank you so much for leaving your kind feedback! We are so happy to hear our Seamless Clip-In Extensions has been the best you've had! These extensions are beyond amazing. They are lightweight and lay flat against your scalp allowing a seamless blend. Buying more colors for a highlighted effect sounds spectacular and this means less damage to your own hair. Extremely exciting. Thank you again! :), Perfect Locks Team ❤️
Had some issues with shipping but customer service helped me figure it out. They were very helpful! The extensions are beautiful and well worth the money. I’ve been wearing extensions for 10; years and this is by far the best quality I’ve received. Looks/feels like my real hair, very natural. I will be repurchasing again in the future. Thank you Perfect Locks for giving me confidence in my hair again! I normally don’t ever write reviews for anything but felt compelled to.
