Thinking about extensions...

Hi Everyone!

I have 3c hair that, comes to the top of my shoulders. My former boss, who does hair, has offered to put Brazilian knot extensions in my hair for the summer. Any thoughts? I love my natural curls but I keep thinking it would be awesome to see how my hair would look long and curly. I'm committed to no heat and have not curled, flat ironed or even blow dried my hair in 5 weeks. But I'm also set on not doing anything else that could be potentially damaging to my hair. I see mixed reviews on this type of extension method with regards to how damaging they are to your hair. Does anyone have any experience with these?
