Especially regarding hair loss, it always requires consultation and examination by a Dermatologist. It is a different case for men and women.
By writing this review, I help you understand where this product serves.
Objectively, it is a very good product that primarily serves the maintenance of existing hair and one should not expect an empty head to be filled, etc.
Personally, I use minoxidil lotion, which I alternate with trichogen lotion.
The product is very pleasant to use and it does not make my hair oily (as for the issue of oiliness, it is logical for each scalp to respond differently).
It has a very nice scent and it absorbs easily. It is worth getting a good shampoo to prepare the scalp as best as possible. The version offers a shampoo that I have not tried.
After use, I feel my hair gaining volume, while over time it seems to benefit from the use of the lotion.

IN CONCLUSION, I give you the following advice: No product performs miracles, but each one has its role and quality. This lotion is very good, but it is one of the many steps in hair care. Diet matters a lot, not having stress, vitamins for hair, good shampoo (not something 5 liters from the supermarket that costs 3 euros), minoxidil that a dermatologist should advise you on, and of course, not expecting miracles where there are specialists to advise you on this matter
