Hello! I’ve been wearing hair extensions for a long time. For context, I’ve purchased 2 sets from Bellami, a set from Luxy, and an inexpensive set from Amazon. Luxy and Bellami are both great and the Bellami ones held up beautifully for about 1.5 years of wearing them about once a month. I wore a combination of Luxy and Bellami for my wedding (no specific reason for combo- I tend to lose the smaller ones for some reason). I was really lucky in that the colors I ordered matched my hair right out of the bag and I was able to dye them darker to match my hair when I dyed my hair darker later on. I would totally recommend either of these brands, but they’re expensive and I can’t compare them to Sally’s because I’ve never purchased from there before.
In terms of the amazon ones, there were pros and cons. They were real hair and I could heat style them. I didn’t try to dye them but it’s my understanding that depending on how they’re processed it can effect the hair dye on them. My main problem was that I wanted these for length and the amount of hair on each clip was very thin. Like 3-4 times less hair per clip than the Bellami or Luxy. If you have thinner hair that might not matter but I had to cut them really short to make it not look weird. Here’s the ones I bought for reference: https://www.amazon.com/dp/B0757C4CLR/ref=cm_sw_r_cp_api_i_3XvoCb6HWYWNC
Hope that helps and congratulations!
