WOW is all I can say! And I think you can see why in my pic. This is ALL NEW GROWTH HAIR!! I have been using this serum daily for about 3 or 4 weeks now, particularly focusing along my hairline, and this morning when I woke up with my hair in a bun, I looked in the mirror and was shocked. Thank you so much, KYIR!
Wow, thank you so much for your amazing feedback! We're thrilled to hear about your new hair growth and that our serum is making such a positive impact. It’s fantastic to see the results you've achieved, especially along your hairline.
Thank you for sharing your experience and for your support. If you have any more updates or need further assistance, we're here for you!
Best,
Team KYIR
Being a platinum blonde is hard enough, let alone living a very active lifestyle day to day as a yoga instructor. Kyir has changed the way my hair feels on hair wash day and has played a key role in the way my hair looks and feels on day four! Sweating is part of my every day life and practice but I never have found a serum that does NOT negatively contribute to my hair after my workouts. My platinum has never looked as healthy as it does now! 🖤
I’ve been using Kyir for the past month and it’s really made a huge difference! Starting to see new growth!
I have been using this for 90 days. My hairline is more full and I have small hairs growing in from the front! I love how it gives me volume as well. I do not need a styling product in addition!
