Great support and email contacts to track success. Happy with the whole experience.

Recently had an issue with USPS with delivery. The issue support staff at collective lavatories were great and helped solve the issue quick and easy

I have noticed a considerably new thickness to my hair since starting the treatment. Additionally, the subscription has proven extremely helpful. Along with ample opportunity to interrupt a month's shipment if necessary. Thanks for such great service, Collective Labs! It's been a pleasure doing business with you!

I’ve been using the serum for about 4 months. I notice a difference in my hairline! My hairdresser even noticed too! The subscription makes it so easy. Another plus is that I have fine hair that tends to be oily, this product is NOT oily or greasy whatsoever! It actually helped balance my oily scalp so I can go two full days between washes.

Every time I’ve had an issue, it has always been resolved in less than 24 hours. Great service.
