Quick tip: Wavy and curly textures are measured when pulled straight, so they'll appear shorter when worn.
Choosing Your Length

Your hair may include 1-2" extra length since our Remy hair has natural ends. Trim to your perfect length or leave natural.

1
Section the Hair2 min Start by parting the hair horizontally at the nape of the neck and clipping the rest of the hair out of the way. Each section should be clean and even to ensure a seamless installation.
-
2
Create a Foundation (Beaded or Braided Track)5 min For a beaded method, thread small silicone-lined beads onto a row of hair, spacing them evenly along the section. Secure each bead by clamping it with pliers. Alternatively, for a braided method, create a tight, horizontal cornrow to act as the base for sewing the weft.
-
3
Measure and Cut the Weft2 min Hold the weft against the prepared section and measure the exact width needed. Cut the weft to fit, avoiding cutting through the stitching to prevent shedding.
-
4
Attach the Weft5 min For the beaded method, lay the weft over the beads and sew it onto the track using a curved needle and nylon thread. If using the braided method, sew the weft directly onto the braid with tight, secure stitches.
-
5
Blend and Style3 min Once the wefts are securely attached, release the clipped-up hair and blend the extensions with the natural hair using a brush or styling tools. Trim if necessary for a seamless look.
- Seal cut edges with fabric glue to prevent shedding
- Use a curved needle for sew-in attachment
- Braid foundation should be tight and flat
- Keep rows at least 1 inch apart
Machine wefts are thicker than hand-tied. For textured hair, use a flat braid foundation and leave extra perimeter hair for blending.

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.

Caring for Perfect Locks' weft hair extensions involves a few simple steps to ensure that they stay looking beautiful and last as long as possible. Here are a few tips to keep in mind:
- Wash your hair as infrequently as possible, and when you do, use a mild shampoo and conditioner specifically formulated for hair extensions. Be sure to stay clear away from the wefted area as any pulling or tugging on the weft could lead to issues.
- Avoid using heat styling tools on high heat settings, and use a heat protectant spray to reduce the risk of damage.
- Try not to sleep with wet hair, and use a satin bonnet or pillowcase to reduce the risk of tangling and matting.
- Avoid using any harsh chemicals or treatments on the extensions, such as bleach, perm or hair dye.
It is important to have regular maintenance with a professional stylist to ensure the longevity of the extensions and to keep them looking as natural as possible. Follow these steps for success!

Every head of hair is unique, and the right amount depends on:
- Wear Time - Temporary or long-term?
- Installation - Subtle blend or full volume?
- Lifestyle - Low-maintenance or high-glam?
- Hairstyle - Natural look or bold transformation?
- Budget - Invest in quality for lasting beauty.
Pro Tip: When in doubt, order extra! Unused hair can be saved for touch-ups or returned if unused.
The number of machine wefts you will need for a full or partial installation depends on several factors, including the thickness of your natural hair, the desired fullness of your hair, and the size of the area you're trying to cover. Also take into consideration the length of hair you're purchase, the longer the length the more wefts you'll need for coverage. As a rough estimate, a full head of hair would typically require 3 to 4 wefts, while a partial installation might only require 1-2 wefts. A more accurate estimation can be made by a hair stylist or professional. It would be best to consult with a stylist to determine how many wefts you need for your specific situation.
Can i color and heat style this hair? """ if you're thinking of coloring your already-colored hair extensions, it's important to keep in mind that these extensions may not take the color as well as natural hair would. This is because the previous coloring of the extensions may affect the final result of the new color, making it difficult to achieve the desired shade. However, with the right hair dye and a professional stylist, it is possible to achieve the perfect color for your extensions! Just make sure to perform a strand test before coloring the entire set of extensions. And remember, many hair extensions, especially those that have been pre-colored, have been chemically treated, which can make coloring them...
Typically, the longer the extensions, the longer the machine weft track will be, and the shorter the extensions, the shorter the machine weft track will be. This is because the weft track needs to be long enough to accommodate the length of the hair being attached to it. It's also important to note that the weft thickness might change depending on the length of the extensions, as longer extensions need more hair to be attached to the weft, therefore the weft will be thicker, and short hair extensions need less hair to be attached to the weft, therefore the weft will be thinner. This can affect the overall weight and volume of the extensions, and the client's preference on how...
There are several ways to make machine wefts last longer: proper installation: make sure that the wefts are properly installed and that they are not too tight, as this can cause the wefts to stretch and weaken over time. Proper care: brush the extensions regularly with a hair extension loop brush to prevent tangling and matting, and avoid using heat-styling tools too frequently. Regular maintenance: have the extensions checked and tightened by a professional every 6-8 weeks to ensure that they are not becoming loose. Use good quality hair: look for high-quality human hair extensions that have been properly processed and treated to ensure that they will last longer, like the hair we offer here at perfect locks! Avoid using...
A beard on weft hair extensions is a small strip of hair that is left attached to the weft when the hair is sewn or bonded onto it. A beard is typically found on the back of the weft, on the side that will be closest to the scalp when the extensions are installed. A beard helps to camouflage the weft. The presence of a beard makes the weft look more like natural hair for a more seamless look. A beard can also add protection to the weft, reducing the risk of tangling by preventing the weft from slipping.

Customer Reviews
Verified photos and videos from customers wearing this hair.
Customers praised this hair for its natural texture that "looks like African American hair that has been permed straight" and blends seamlessly with relaxed hair. While quality is consistently rated excellent, some experienced significant shedding and matting. The texture becomes silkier with high heat. Price point is a concern for some shoppers.

I honestly use nothing else. I would literally DIE if they stopped selling this product. Every single hair stylist that installs this hair has sooo many compliments and wants to know where I buy this awesome hair. Personally I feel this is the best hair on the market. True 100% Remy! The relaxed texture is a God Send! It blends flawlessly with my relaxed hair when flat ironed. I really cannot be happier. Hopefully one day we'll get some ombre colors in this texture (wink wink;) lol. But either way I'm ecstatic. I use the wefts and clip ins in this texture and will try whatever else they have in this texture. This hair is a worthwhile investment.

This hair truly looks like African American hair that has been permed straight. It's very very nice! With that being said, if you flat iron this hair on high heat, it will become very silky and shiny, like Asian hair (so be careful unless you want that texture). I experienced shedding, a lot. The closure for this same hair type shed so much that I had balding spots on it. Customer service was impeccable and they shipped me a new one within 2 days. The second is holding up much better (I also sealed the knots), however the shedding of this hair in general is bad. I hope the tracks will last me a year or even more like I've read about other hair textures through this company. If you're looking for hair that looks like permed or treated AA hair, this is very good!
I ABSOLUTELY love this hair!! It is by the best Yaki on the market. If you are looking for a more natural texture i highly recommend this brand.
I have an overall great experience with this hair! It matches my hair texture perfectly! I’m really impressed with Perfect Locks!
Really good quality and texture
This hair is great. Actually some of the best that I have used
I love this hair, absolutely love it!! It looks so much like my own hair. It's easy to color, not very little shedding -- its great! The only reason I gave it 4 instead of 5 is because of the price. I don't like to see that the hair closest to African American is the most expensive hair to buy.
Disappointed in the texture feel of relaxed straight. Looks beautiful...but sheds quite a bit and becomes matted at the nape.....Not accustomed to shedding and matting with PerfectLocks.....all of this happened after installation...was totally caught off guard....hope this helps someone.
Great experience, great customer service quick & so easy. Will purchase again & definitely recommend.
I brought the product several times and love it.
I have purchase many brands of hair this hair is by far the best... people cannot tell the difference. The quality is the best. wash it over an over and it looks better with ever wash... I'm sold. Love the natural Yaki texture... It matches my hair perfectly.
I loved the texture of the hair. It was a good match very similar to my own. My only concern was the thickness of the weft. Would be perfect if the weft was thinner.
The texture is a bit silkier than expected which makes it an imperfect blend for natural 4b/c hair. It also had a bit of an odd smell.
The hair was absolutely gorgeous. It reminds me of how my hair was when it was healthy and long. Other hair that I have purchased while trying to regrow my own hair is reminiscent of baby doll hair. This hair is truly like my own hair. Thank you perfect locks.
Really love the hair, doesn’t shed that much and when I wash it and flat iron it return back to silky straight.
The hair is wonderful.
I love the Relaxed Straight. It’s a perfect match to my natural flat ironed hair. It’s very soft and manageable. I’m ordering more. I absolutely recommend it!
