Good but smells weird
a year ago
I enjoy the way that the filler serum makes my hair feel thicker, but it smells like a combination of nail polish, nail polish remover, and perm solution. Is it supposed to smell this way or has it gone bad?

I used this on my grey hair while it was dry because I was anxious to try it. My hair was so full and thick! Both visually and how it felt in my hands. Really a big difference and my husband noticed and wanted to try it too. We both have long grey hair and we take very good care of our hair. This made a big difference for both of us.

Smells good but I haven't seem much of a difference in my hair since I started using the product. A little goes a long way, it is a little sticky and greasy. I probably would not purchase again

Hello user123859593! We are pleased to hear that the Hair Filler + Vitamin Cg Strength Repair Serum smelled great...however, we are disappointed to hear you did not notice the results you were hoping for. The results should be visibly smooth and healthy-looking hair.

I am not sure if this product did anything for my hair. I don’t think using it for a month is long enough to notice the difference. I don’t feel any improvement with my hair since using this product.

I love the scent! Very refreshing. It makes my hair feel so soft after each use. I don’t put too much because it can weigh your hair down. My hair is very long so using serum is a must

This serum smells good and although I would like to use it more often because my hair feels silky, it also leaves my scalp feeling and looking oily.

I really like this product! I had never tried a hair serum previously so I don't have much to compare it to but I did enjoy this and I liked the scent of it as well. I think it did a good job!
Q: I know this is the final step of my routine, but I’d like to know how often I can use it. Is it okay to use it every day, or should I only use it every time I wash my hair? Please let me know if yes or no 🙌

Q: Can I use this with a heat protector? Should I use this & leave it in before going in with a heat protector?

A: Hi Nice92! Thank you for inquiring about the order of use when using Fructis Hair Filler Strength Repair Serum. This is the final step in using the system, and should not be rinsed out. You can apply your heat protector, before using blow dryer, flat iron, etc.

Q: My hair is 100% gray (white actually). Will this line of products work on gray hair? If not, do you recommend any of your products for thinning gray hair? Thanks.

A: Hey there Jezebellydancer . Thanks for reaching out about using the Hair Filler + Vitamin Cg Strength Repair Serum. This serum works best as the 4th part of the Hair Filler + Vitamin Cg system to strengthen and repair thin, weak hair of any color (or lack of color) . To thicken fine, thin hair, use the Grow Strong Thickening shampoo and conditioner.

Q: How much of the product should I be using (dime-size, quarter, etc)? Also, is it applied from roots to ends, or more to just the ends? There are no instructions!!
Lilypad132 years ago
2 AnswersAnswer this Question
A: I would avoid the root area as you shouldn’t need bond filler yet to that part of the hair shaft and it will likely make your scalp oily. Start with dime size for chin to shoulder length thin hair, adding more for thickness and length. And as you see fit. Back off if you notice oiliness.
