Straight Halo Extensions Length Guide
Straight halo extensions from Thathair come in four different lengths:
There is a style that fits every hair type, whether you want dramatic length or a modest volume boost.

Benefits of Straight Halo Extensions
For people who wish to add length and volume but at the same time keep their natural appearance, 16-inch halo hair extensions are the best option. They give you a fuller, more confident look and are great for thin or fine hair.
Compared to the 14-inch option, 16-inch extensions give you a slightly greater length and a few more styling options. They are ideal for daily usage because they go well with short to medium hairstyles and give the ideal amount of length and volume without making you appear overly "done up."
Furthermore, a 16-inch straight halo seems longer than a 16-inch curly or wavy extension because straight hair appears longer than curly or wavy styles of the same length.
Let's Find Your Perfect Color
Getting that flawless finish starts with the right color. To make your halo extensions blend beautifully, focus on matching the shade to the ends of your natural hair, not the roots. Why? Because the halo sits underneath, and that’s where the color matters most.
Not sure between two tones? Going slightly lighter often gives a softer, sun-kissed effect that still looks natural.
We’ve made it easy to find your match—just explore our selection of base colors, each available in multiple undertones for the perfect fit:

Frequently Asked Questions
How to blend halo extensions with layered hair?
Choose a length that matches your longest layer. If needed you can slightly trim the extensions.
If I want both volume and length what option should I choose?
To maintain a natural look, one halo is enough if your hair is medium thickness. For thin hair or extra volume, layering two halos of different lengths (e.g., 16” for volume + 20” for length) creates the desired effect.
How do I prevent my halo from slipping, if I have silky hair?
Try backcombing the roots at the crown before placing them. It adds grip. A hair spray or dry shampoo also helps with that.
Can I wear my halo with a high ponytail or updo?
Yes, but with some adjustments. Secure the halo lower on your head and leave the top layer of your natural hair out to cover the band.
What products should I use (or avoid) to keep my extensions looking fresh?
Use sulfate-free, alcohol-free shampoos and conditioners. Avoid heavy oils or silicone-based products, as they can weigh down the hair.
Can I sleep with my halo extensions in?
No. Always remove your halo before sleeping to prevent tangling. You can store it in a silk bag or hanger.
Will my halo stay in place if I’m dancing or working out?
Yes, if they are properly secured. Teasing the roots and using a light-hold hairspray help with grip. For high-movement activities, opt for a half-up style to keep the halo in place.
How do I take care of my straight hair extensions so that they last longer?
Wash them with sulfate-free shampoo only when it’s absolutely needed. Better let them air dry rather than blow drying, and store them in a box to avoid tangling or damaging.
Can I curl my straight halo hair extensions?
Yep! You can style it just like your own, they are heat-friendly. But as you would do with your natural hair, make sure to keep the heat at a reasonable level to avoid damage.
Can I dye my halo extensions?
Although not recommended the answer is yes. You can dye them, but only go darker, not lighter—bleaching can damage your extensions. If you need a different shade, we are here to help you easily exchange your product and get you a new one, that fits you better.
Will a halo extension work if I have thin or fine hair?
Yes! Just make sure to place the halo a little lower on your head so it blends in better. You can also tease the roots a bit for extra grip. If your hair is super fine, a few strategically placed bobby pins can secure your hair better and help keep everything in place.
