01
Section Hair

Frequently Asked Questions
It’s all about consistency. Visible improvements in hair density typically require at least 90 days of consistent use. In the first few weeks, your scalp begins to rebalance, and some may notice a brief increase in shedding as follicles shift into a healthier cycle. Around three months, hair starts to look fuller, with less noticeable thinning. With continued use beyond three months, volume and density continue to improve as stronger strands grow in.
Our Redensify Reset Shampoo is formulated to be gentle and does not contain ingredients commonly avoided during pregnancy or breastfeeding. However, we always recommend checking with your healthcare provider before starting any new personal care product. Our Redensify Treatment Serum contains ingredients such as a retinoid and saw palmetto, so it should not be used during pregnancy or while breastfeeding.
We are happy to report the answer is no! Kerativ formulas were specifically designed for fine and thinning hair, where heavy products can easily weigh hair down. The lightweight textures absorb quickly and provide hydration without leaving a greasy or oily residue on the scalp or hair.
Applying to a clean scalp is ideal, as it allows the formula to reach the scalp more easily without being blocked by excess oil or buildup. However, consistency matters most. The Redensify Treatment Serum was designed to fit easily into your routine, so it can also be applied between washes to desired areas, even if you use styling products or wash your hair less frequently.
With typical daily use, one tube usually lasts about 6 weeks. The formula is designed to be applied directly to thinning areas, so a small amount goes a long way.

This scalp serum was a pleasant surprise. The formula is lightweight, non-greasy, and didn’t cause any irritation on my sensitive scalp. Although I haven’t noticed significant improvement in my hair issues yet, I value that it feels clean and nourishing with each use. I plan to keep using the rest of the bottle to allow more time for potential results.

Application for the product is easy. My hair has been growing back! I do see difference since I have started.
- AANRated 4 out of 5 stars2 months ago4 Stars
I used product for 3 months; easy to use and love that it is fragrance free and I forget after application that i applied it. I don't think I have seen full meaningful difference yet from it....maybe my hair is a bit fuller and some new hairs growing but I have a ways to go. Given the ease of use, I am willing to try longer.

This product feels amazing on the scalp and is extremely easy to apply. I saw baby hairs growing all over after only a few months of use. The product isnt sticky at all and left my scalp feeling cleaner and refreshed.

I honestly loved this product so much! The first month I didn't notice too much of a difference, but after three months of consistent use my hair is visibly thicker with increased density. I also notice less hair shedding when I am in the shower too. I would definitely love to keep using this product long term!
