[EX Q]: I have been struggling with lack of energy and weight gain since having a partial thyroidectomy 2 years ago. I am on a super low dose of levothyroxine and my blood work always comes back normal even though I still struggle with symptoms. thyroid support has changed my life. In one month of taking feel so much better- more energy and motivation to work out again.

[EX Q]: Mine leaked after using it for a week. I thought it was surely something I did wrong, but everything was nice and tight and yet it leaked. Unfortunately, it was in my bag at the moment, so it leaked all over everything. What a shame! I was really enjoying it... well until it leaked. Not sure what happened, so can't give you more details, but certainly is not something I would try again.

[EX Q]: I bought these for my daughter who has long hair. They are great quality and easy to use. I put them in her hair all the while thinking they wouldn't be very good for a adult with thick hair but there were 6 left over so I pout them in my hair. I was very impressed. The next morning there ones I'd used stayed in and left very nice curls. I'd recommend these to anyone and would definietly purchase again.
