I loved the Donna Bella 22 inches curly I-tip hair extensions when I unpacked the package of it. The reason lies in that the hair looked and felt like my natural hair.
I had it cut a little bit so that it could blend better into my natural hair. I always take good care of the extensions, brushing it with extensions brush, shamppoing and conditioning it well, air drying or towel drying it all the time. Although it is claimed to be dyeable and heat resistant, I never dyed , straightened, or curled it. My natural hair will be fragile after chemical or heating process, so I believe that hair extensions will be more fragile if undergoing such process.
So far, the hair extensions still keep in good shape. I have kept it for about one month.
