My friend got hair extension done; however, her hair looks even more frizzy now. I want to know about some cheap clip on hair extensions now as I am no more inclined to real hair extensions after noticing my friendâs condition now. Can somebody please tell me how to look after hair extensions so that it remains shiny always? I would also like to know if cheap hair extensions would damage my real hair at any point of time! Can anyone please tell me about it in detail? I would be thankful!
