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.

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!!

These extensions are my favorite! Look no further than sunny hair. The new weft where the hair is attached is so soft you can even feel it. And it’s so much easier to blend when doing a ponytail or half up half down style.

Not bad for the price, they are a little thin so if your hair is very thick get 3 packs! They straighten and curl great.

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!!

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!
