Award-winning active ingredient

Redensyl was awarded the In-Cosmetics Silver Award for innovative active ingredients in 2014 and works as follows:

1) soothes the scalp and is anti-inflammatory.
2) stimulates and strengthens the stem cells of the hair follicles.
3) has a positive effect on the cell division of the hair follicle stem cells and promotes their reproduction.


Redensyl® reactivates inactive hair follicles and thus promotes hair growth. The first (measurable) results can be expected after 6–10 weeks. Then the changes begin to become visible. The progress of the process can also depend on the genetic disposition and several environmental factors (lifestyle, diet, etc.).

Swiss made

The Beneva Black Hair Loss Tonic was developed in Switzerland under the direction of Dr. David Faivre and developed and produced in collaboration with Cosmetique SA.

The combination of Redensyl, Vegetal Glycerin, Provitamin B5, Ginseng Extract, and caffeine promises exceptional quality and the major goal of reducing hereditary hair loss and stimulating hair growth.

Study confirms success

In a clinical study on the effectiveness of Redensyl (Ex-Vivo) to increase the hair growth rate in the case of hereditary hair loss, the following results were obtained over a period of 3 months:

-> 214% more hair growth
-> Thicker hair on 85%
-> up to 28,000 new hairs
-> 8% thicker hair
-> 70% would buy the product.

  1. Hurbert -

    Looking forward to the results. Delivery and application everything fits great

  2. Luca -

    Fast delivery and nice product. I'm curious.

  3. Sam -

    I have already tried a number of hair restorer but none seems as plausible to me as this one. Use it too briefly to see results.

  4. Andreas -

    Great service - good delivery.

  5. Martin -

    I have round hair loss that is hereditary. I have been using the Beneva Black Hair Loss Tonic for 4 weeks now and I am thrilled. Not only is the hair loss stopped, but new hair has grown and become thicker, so it is more visible. I can only recommend it!

  6. Sonja -

    Great product, I'm 53 and have been using it for about 3 months. I can feel how I have more hair and my hair no longer looks shabby. Can recommend the product to every woman.

  7. Helen -

    My mother already had hereditary hair loss. After the menopause, my hair became very thin. With the hair loss tonic I was able to regain some volume. Would recommend. Incidentally, the hyaluronic acid products too.

  8. Habib -

    I don't know yet but it already works

  9. Herbert -

    This is now my 2nd course. Got the tonic from my wife half a year ago. I was skeptical at first but after about 6 months of use I can see a constant improvement for myself. I firmly integrated the application into my everyday life and will now continue with the next treatment. A clear recommendation from me!

  10. Sasha -

    Save your money on a hair transplant

  11. customer -

    Makes hair greasy

  12. Holger -

    I've already tried a lot. I was probably allergic to minoxidil. Now I have landed here and after 1 week of use I was thrilled. Tolerance is great and the hair feels firmer and stronger after application and drying. A first nice effect. Now I hope for further growth spurts in 3 months at the latest. A recommendation for me, I think it's definitely worth trying.

  13. Timo -

    I have now tested the product for a few days and wanted to leave a review for the others. ? I personally have the feeling that this product helps me and slows down and even counteracts hair loss. I see a few sprinkling hairs! Let's see how it goes on. In any case, pleasantly surprised so far.

  14. Erhan Sisman -

    Super product the hair loss serum. At first I was skeptical, but my photo documentation showed me that after 50 days my hair had become thicker. Can only recommend this product. Now I'm going to test the Beard Growth Tonic

  15. Satinka -

    I am consistently enthusiastic although I was really very skeptical at first. I take the product very well. No itching, no redness. After a very short time I notice a clear change. The hair looks much fuller and new hairs seem to grow back. The smell is also very pleasant. The price is very high - but if the desired effect is achieved by continuing the treatment, it is definitely worth it! I will definitely continue the treatment and I am convinced that the product is definitely worth the money.

  16. Jessica -

    Since I suffer from hair loss and finer hair, I like to try to support my hair so that it gets an optimal breeding ground for new growth. I therefore use the product as an aid to optimally support this process. As soon as you open the packaging, you notice the high-quality presentation of the product, but without neglecting environmental considerations: no additional plastic is used, which is not even taken for granted these days. From testing myself, I find the product effective for me, but this probably depends on how you react to the active ingredient. The hair looks more grippy to me, so I have the feeling that new hair has been added. A car cannot drive without high quality oil, yes, how can our hair grow if we don't pay it the attention it needs. A little tip: The product consistency is liquid, so I would recommend that you do not apply the product to your hand beforehand, but rather directly onto your hair
