Texture
Our Blue Cobalt Color Straight Weft is a bold Remy human hair option for buyers who want a clean straight look in a standout fashion shade. It suits salons, resellers, and brands looking for straight human hair weft extensions with thick ends and a neat double weft finish.
Why Buyers Choose It
This weft combines a vivid blue cobalt tone with a smooth straight texture that looks sleek and modern. The double weft construction helps create a tighter, neater bundle with better fullness and added buyer confidence.
The hair is shown with natural shine, thick ends, and a clean overall finish. It is also presented as tangle free and shedding free, which matters to buyers focused on consistent quality.
Benefits for Styling and Daily Wear
Straight weft hair is practical for polished daily looks, layering, and custom extension work. The texture gives a smooth appearance that is easy to match with sleek styles and statement color applications.
This product is also shown as healthy-looking and dyeable, which gives buyers more flexibility for customization. Thick ends help the hair look fuller from top to bottom instead of thin at the bottom.
Hair Extensions Before And After
Why Vietnamese Hair
Vietnamese hair is valued for its softness, strength, and naturally smooth movement. For straight weft products, these qualities help the hair look cleaner, feel more manageable, and maintain a more refined finish.
Remy human hair is especially preferred for wefts because it supports a more consistent appearance when handled and maintained properly.
Styling Options
This straight weft works well for sew-ins, custom wigs, and other extension applications that need a sleek finish. The cobalt blue shade is suitable for bold salon looks, creative color collections, and statement hair designs.

Can hair be dyed?
"""Our extensions consist entirely of 100% human hair that has undergone a unique dyeing process. While our products are designed to accommodate color application, we highly recommend seeking the advice of a skilled and experienced colorist. It's important to note that dyeing could potentially impact the longevity of your Great Hair extensions and could result in damage if not executed correctly. We also strongly advise against attempting any form of lightening or using bleaching agents. For our Balayage or Ombre sets, we must emphasize that dyeing is not recommended. These particular sets have undergone multiple processing stages, which makes them less suitable for dye application. Due to their extensive processing history, these sets do not respond well to dyeing attempts."""

HOW DO I WASH MY EXTENSIONS?
The best way to wash your extensions is by gathering all the hair strands together into one ponytail. Then run the ponytail under lukewarm water. Squirt a nickel size worth of shampoo into your palm and lather into hair. If needed, rinse and repeat until the shampoo begins to lather. Next, apply conditioner combing it through the hair using a wide tooth comb to distribute the product evenly and rinse again. Finally, we recommend letting your extensions air dry by using a hanger. The picture below will show you what your hair extensions should look like after they dry. We recommend the Daily Duo-Pure Care Shampoo & Conditioner for Human Hair by BeautiMark, and Cleansing Duo-Shampoo and Conditioner for Synthetic Hair by BeautiMark.
-
WHEN SHOULD I WASH MY HAIR EXTENSIONS
We recommend washing your hair extensions every 6-8 wears using the appropriate product for synthetic or human hair. Extensions don’t accumulate oils the way our natural hair does so washing it more often than this can weather the fibers and damage your extensions.
