HOW TO CHOOSE THE RIGHT LENGTH AND NUMBER OF WEFTS — PLUS HOW TO TAKE CARE OF YOUR HAIR EXTENSIONS
So you've decided to invest in weft hair extensions — amazing. But now comes the part that trips a lot of people up: how long should they be? And how many wefts do I actually need? ♡
If you're new to extensions, these questions can feel overwhelming. There are a lot of opinions out there, and the answer really depends on your hair, your goals, and how you want your extensions to look and feel. Let's break it down.
How to Choose the Right Length for Your Weft Extensions
The most important thing to know about choosing a length is that extension length is measured when the hair is straight. If you have any wave or curl to your natural hair (or if you plan to curl your extensions), the finished look will appear shorter than the stated length.
Here's a general guide to help you visualize:
16 inches — Falls around the collarbone. This is a great option if you're looking for added fullness and thickness without a dramatic length change. It blends naturally and gives you that "my hair but better" look.
20 inches — Falls a few inches below the collarbone, around the mid-chest area. This is one of the most popular lengths because it adds noticeable length while still looking natural and manageable.
22 inches — Falls around the bottom of the chest. A beautiful length for that long, flowing look without being over the top.
24 inches — Falls at the waist or just above. This is a statement length — dramatic, full, and head-turning.
A good rule of thumb: if you're unsure, go shorter than you think. You can always go longer next time, but extensions that are too long for your frame can look unnatural or feel heavy. Think about your height, your natural hair length, and how much of a change you're comfortable with.
How Many Wefts Do You Need?
This is where it gets personal — because the number of weft extensions you need depends on a few things: your natural hair thickness, the look you're going for, and the method of application.
Here's a general starting point:
Fine hair — If your natural hair is on the thinner side, you'll typically need fewer wefts. Going too heavy can put unnecessary weight on your hair and look unnatural. Start lighter and add if needed. 2-3 wefts per row.
Medium hair — This is the most common hair density, and a moderate number of wefts will give you a full, natural-looking blend of both length and volume. 3-4 wefts per row.
Thick hair — If you have thick natural hair, you'll likely need more wefts to match your density and get a seamless blend. The extensions need to keep up with what you already have. 4-6 wefts per row.
If you're working with a stylist, they'll help you determine the right number based on your hair and the specific look you want. If you're buying for yourself, start with a standard set and see how it feels before adding more.
One of the best things about XO Lover weft hair extensions is that they're sold individually. That means you're not locked into buying a pack with more wefts than you need — you can customize your order to match your exact hair type and goals.
How to Take Care of Your Weft Hair Extensions
You've invested in ultra-premium weft extensions — now let's keep them looking that way. Proper care is the difference between extensions that last a few weeks and extensions that hold up for months. Here's what you need to know.
Washing
Don't overwash your weft extensions. Two per week is plenty for most people. Use a sulfate-free shampoo and a lightweight, hydrating conditioner. Sulfates strip moisture from the hair, and since extensions don't receive natural oils from your scalp the way your own hair does, keeping them hydrated is essential.
When you wash, be gentle. Don't bunch or scrub the wefts — work the shampoo through in a downward motion and let the conditioner sit on the mid-lengths and ends for a few minutes before rinsing.
Brushing
Brush your weft extensions every day — but do it the right way. Use a soft bristle brush or a brush designed specifically for extensions. Always start from the ends and work your way up to the roots. Never rip through tangles from the top down — that's how you damage both the extensions and your own hair.
Hold the weft at the root when you brush to avoid pulling on the attachment point.
Sleeping
This one makes a bigger difference than people realize. Before bed, gently brush your extensions and put your hair in a loose braid or low ponytail. This prevents tangling overnight. A silk or satin pillowcase also helps reduce friction and keeps both your natural hair and your weft extensions smoother.
Never go to bed with wet extensions. Always make sure they're fully dry before sleeping.
Heat Styling
Because XO Lover weft extensions are 100% human remy hair, you can curl, straighten, and style them with heat — just like your own hair. But always use a heat protectant, and try to keep your tools at a moderate temperature. Just because the hair can handle heat doesn't mean you should max out your flat iron every day. Lower heat preserves the hair's integrity and extends the life of your extensions.
Swimming and Sun Exposure
One of the benefits of XO Lover ultra-premium weft hair extensions is that they're sunscreen safe — avobenzone does not affect or alter the color of the hair. So you can wear your SPF without worrying about your extensions.
For swimming, try to wet your hair with clean water before getting in a pool or the ocean. This helps prevent the hair from absorbing too much chlorine or salt water. After swimming, rinse your extensions with fresh water as soon as possible and apply a leave-in conditioner to keep them hydrated.
The Bottom Line
Choosing the right length and number of wefts doesn't have to be complicated. Start with what feels right for your hair and your goals, and remember — you can always adjust. The most important thing is investing in quality weft hair extensions that hold up over time. 100% human remy hair, double drawn, full-cuticle, silicone and brass free. That's the standard.
And once you have them? Take care of them. Wash gently, brush daily, sleep smart, and protect from heat. Your extensions will thank you. ♡
