Buyer BEWARE!!
Buyer BEWARE! I wish I would have taken the time to look at reviews prior to making this purchase, as I see my negative experience is shared. I am only guilty of not honing in on the very specific details of the 90 day return policy; I did not think that was extremely necessary. In my other experiences dealing with reputable companies, who truly care about customer satisfaction, returns are never an issue. Unfortunately this is not at all the case with KilgourMD. Though the price was way over my comfort level, I was eager to try due to their claims, and the fact that I could (at least I THOUGHT I could) return the product if I was not pleased. I realized very early on that I was not going to be able to get past the unpleasant smell of the product, though I sure gave it an attempt. I first reached out to them requesting a refund after 46 days of use. Not only was I not seeing results, again the smell to me was intolerable, and the primary reason for returning. I would think their primary concern would be customer satisfaction, regardless of the reason why. However, the reply I received did not even inquire as to "why" I wanted a refund, but only stated that I could not return the product until consistent use over a full 90 days. I asked if there was anything further I needed to know regarding the return after the 90 days of use, to which would have been the perfect opportunity for them to fill me in on this next part, though they conveniently omitted this important information. Upon my second attempt at trying to return the unused products (4 bottles total) following over 90 days of use, I was then told that my request was now beyond the 90 days, and therefore I was no longer eligible for a refund. I was told the email refund request had to be sent on the EXACT date following 90 days from the order date. Which is also absurd for those (like myself) who were not able to begin using the product until a time after receiving. So ultimately, not even an accurate depiction of 90 days of use for results anyway. To be so rigid as to expect customers to send this email on ONE date, is very unreasonable, though certainly frees them of honoring their stated return/refund policy. It appears the one thing they are good at is responding to negative posts, in an attempt to make it seem like they care, and attempt to try to salvage their reputation. Too little, too late. My recommendation is to save your money, spare yourself frustration, and continue your search for a hair product that works, and with a company who cares about customer satisfaction and honors returns. Off to the landfill are my four unused/unopened, very expensive bottles of product...

Thank you for taking the time to share your feedback. We sincerely apologize for the frustration and any miscommunication surrounding our 90-Day Trial Guarantee and refund process.
We understand how disappointing it can be when expectations and policy details are not communicated as clearly as they should be. In reviewing your experience, we recognize that there was an opportunity for us to provide better clarification regarding the timing requirements of the guarantee, and we're sorry for any confusion this caused.
While our 90-Day Trial Guarantee applies exclusively to The Prevention Scalp Serum and The Treatment Scalp Serum and is intended to allow customers adequate time to evaluate results, we never want a customer to feel unheard or dissatisfied. As a result, we have made an exception and have granted a refund for your order.
We also understand that fragrance preferences are highly personal, and we're sorry that the scent of the product made it difficult for you to continue using it. We appreciate you giving the product a genuine try and sharing your honest experience.
Your feedback is valuable and helps us improve both our communication and customer experience. We appreciate the opportunity to make this right and wish you all the best in finding a hair care solution that better meets your needs.

Friendly Staff when had a request or questions
My request to receive this product every 2 months vs every month was easily rescheduled, and when it was discovered the serums were already on it's way, they issued me a partial refund! This was all accomplished within an hour of time during my work, with a very friendly attitude as well. The best part is that these serums really do work with consistent use! Thank You!

I got a notice that my next shipment was en route and I realized I have plenty and that I won't be in town for the next several months. Within an hour after reaching out to customer service, I received a response and was able to pause my subscription pretty seamlessly.

So far so good!
It's still early to determine outcome but after 1 1/2 months of using your shampoo/conditioner, it seems as though I have less hair loss. I just hope that continues. What I DO notice is that my head no longer itches like it did constantly. THAT is huge! My head also feels so refreshed when I wash it. So far I love this product.

Thank you for sharing your experience! We're delighted to hear that after just six weeks of using the shampoo and conditioner, you're already noticing less hair shedding and significant relief from the constant scalp itching you were experiencing. A healthy, comfortable scalp is an important foundation for healthy hair, so it's wonderful to hear that your scalp feels refreshed and balanced after each wash. While hair growth and retention results can take time, we're encouraged that you're already seeing positive changes and hope your progress continues.

You may want to start with a dermatology consult not a broad internet ad
Was it expensive? Yes but many things that make us feel better about our appearance are, so this didn’t bother me. Shipping was communicated well and the items arrived on time. I had seen comments about light or gray hair turning yellow, and how using clarifying shampoo or the purple shampoo for gray hair might mitigate that, as might using the product on clean hair in the event that product buildup may be contributing to yellowing of hair with use of the product.
I followed the directions for the product exactly as written. I also used clarifying shampoo 1-2 times a week, as well as using purple shampoo my usual 2x/week. Despite this, my grey hair started to turn yellow. I added a purple conditioning mask for my hair once a week as well. My hair never turned the orange or very yellow as some people described, but it was nonetheless noticeable – my hairdresser commented on it every time I came into the salon – so it was of some concern to me.
More importantly, my hair continued to shed as it had prior to using the product and no new hair growth ever emerged. I did continue to use the product for the full three months, although I discontinued my subscription so that I would not get another order before that three months was up.
It took fully two months for the yellow to be out of my hair once I discontinued using the product – both in terms of fading and by way of haircuts (my hair is very short so as far as haircuts go that was probably doing the bulk of the work). Two months after I stopped using the product my hair had stopped shedding, and recently has looked/felt less thin, and when I look back at what’s been going on in my life – a decrease in work and personal stress, a change in diet & medications, etc. - it’s clear that I probably should have had a consult with a dermatologist who would’ve taken a good health history and provided guidance toward possible lifestyle changes (stress etc) and made appropriate product recommendations specific to my situation. I took a chance because I felt bad about my appearance, instead of considering my whole self. I don’t think I will do that again.

Thank you for taking the time to share such a thoughtful and detailed review. We’re sorry to hear that you experienced yellowing of your grey hair and that you did not see the shedding improvement or new growth you had hoped for after using the product consistently for three months.
We understand how frustrating and personal hair concerns can be, especially when you are investing time, care, and hope into a solution. While results can vary from person to person, we appreciate you sharing the steps you took and your reflections on the role that stress, health, diet, and other lifestyle factors may have played.
We’re glad your shedding has since improved and that your hair is looking and feeling less thin. Your feedback is genuinely valuable, and we wish you continued improvement and confidence in your hair journey.

I actually really love these products
I actually really love these products. I’m 2 months in and definitely see hair growth and less hair fall. I love the Shampoo set. And the serums are very nice. They do leave residue on the hair making my hair washing more often. Maybe I am using too much, but rather get every bit of my roots nurtured. The only other downside is that it might be staining my highlights so I have to be careful not to get it on those areas. Otherwise I love it and I’m not stopping this process!!!

Thank you for sharing your experience! We're thrilled to hear that after two months of use you're already seeing less shedding and new hair growth. It's especially wonderful to know that you're enjoying both the shampoo set and the serums as part of your routine.
We appreciate your honest feedback regarding the residue and the effect on your highlights. Applying a little less serum may help reduce buildup while still allowing you to target the scalp effectively. For customers with lightened, highlighted, gray, or white hair, we also recommend taking care to apply the serum directly to the scalp and minimizing contact with the hair shaft whenever possible. Using a purple shampoo 1–2 times per week can also help minimize any unwanted yellowing or discoloration and keep highlights looking fresh.
We're so grateful to be part of your hair growth journey and are excited to hear that you're seeing positive results. Thank you for your support and for trusting KilgourMD!
