    Detangling: Use a wide-tooth comb or a professional detangling brush. Start gently from the ends and work your way up to the roots to avoid breakage.

    Washing: Use a sulfate-free and phosphate-free gentle shampoo. When cleansing the scalp, allow the shampoo to rinse through the lengths naturally.

    Conditioning and Treatment: Apply conditioner and a hair mask regularly. After washing, use hair oil to nourish and keep extensions soft and hydrated.

    Drying: Do not sleep with wet hair. Gently pat dry with a towel instead of rubbing. Air-dry whenever possible and avoid excessive blow-drying.

    Sleeping: Before bed, loosely tie hair into a ponytail or braid it. A silk pillowcase or sleep cap is recommended to reduce tangling and friction.

        Customer photo review of Best Genius Weft Extensions for Thin Hair 100% Virgin Human Hair Off Black#1B

        I used to use tape in extensions and then went without for a while. I wanted more fullness as my hair is already long so I got the weft 22 inch in 1B. The color match is perfect and I love this hair!!! I think I have a normal amount of shedding and I was able to use the same extensions when I got them moved up again! My stylist was even impressed!!

        Best Genius Weft Extensions for Thin Hair 100% Virgin Human Hair Off Black#1B

        Customer photo review of Best Genius Weft Extensions for Thin Hair 100% Virgin Human Hair Off Black#1B

        I ordered this extension because I wanted to try doing long ponytails and my real hair isn't long enough to achieve it. After browsing for extension that feels and looks like real hair, with also good reviews I've decided to purchased this one and it's absolutely the best!! But if you have a very thick hair you might have to consider buying 4 sets as you can see in the picture it's too thick from the top but that's cause of my real hair. Other than that I am still be able to achieve the look I've wanted, quality didn't disappoint and definitely buying again!!

        Best Genius Weft Extensions for Thin Hair 100% Virgin Human Hair Off Black#1B

        I'm so happy I found the hair! It's exactly what I needed to add volume to my thin hair. It's easy to style, and it stays looking fresh all day long. I've worn it to weddings, dates, and even to the gym, and it holds up perfectly. I've already bought two more sets, and I'm planning to get a few more in different colors.

        [Virgin Hair] Best Genius Weft Extensions 100% Human Hair Black #1B

        I was looking for hair that would blend seamlessly with my own, and Sunny's delivered. It's lightweight, so I don't feel any discomfort when wearing it all day. The color is exactly what I ordered, and it hasn't faded at all after a month of use.

        [Virgin Hair] Best Genius Weft Extensions 100% Human Hair Black #1B

        I've tried so many different hair extensions over the years, and this one from Sunny is by far my favorite. The texture is exactly like my natural hair, so it blends seamless without anyone noticing. I can straighten it, curl it, even dye it a little darker and it holds up great. No weird smells, no excessive shedding, just perfect hair that makes me feel confident every time I put it on. I already told all my friends about this shop!
