Frequently asked questions
How soon can I see a difference?
In the study conducted with ivaHAIR Strong Hair Serum, the first signs of reduced hair loss were assessed after 3 months, and full results after 6 months. It is a product for a consistent routine, not for week-to-week results.
Do I need to use it every day?
Yes. Daily application is part of the product protocol: 2 droppers on a clean scalp, no rinsing, in courses of at least 3 months.
Will it make my hair greasy or sticky?
The formula has a light, watery, leave-in texture. In reviews, the fact that it doesn't leave hair oily or sticky is one of the product's advantages.
Do I apply it to the scalp or the lengths?
To the scalp, at the roots, not to the lengths of the hair. That is where the serum should be distributed and gently massaged until absorbed.
Is it suitable for men too?
Yes. The clinical study included both women and men, and the product is intended for hair prone to shedding and loss of density, regardless of gender.
Is it suitable for seasonal or postpartum hair loss?
Yes. It is recommended for diffuse and temporary forms of hair loss, including seasonal and postpartum. For progressive hair loss, clearly thinning areas or suspected androgenetic alopecia, the serum can complement your dermatologist's recommendation.
What results were measured after 6 months?
The clinical study reported +35% density, +42% cumulative average thickness and -27% hairs in the regression phase.
How long does one bottle last?
One 50 ml bottle lasts about 6 weeks with the recommended use.
Can I use it if I already apply minoxidil or follow another anti-hair-loss treatment?
For topical or systemic drug treatments, the order and combination schedule should be determined with your dermatologist.
What do +35% density and +42% cumulative thickness actually mean?
These are results measured with TrichoScan® after 6 months. +35% refers to hair density, and +42% to cumulative average thickness — an indicator of hair mass in the assessed area.
If I stop the serum, will I immediately lose all the results?
The study describes the progress during the usage protocol, but does not support the claim that results are permanently maintained after stopping. For a maintenance strategy, frequency and duration should be adapted to your needs and the cause of the hair loss.
When should I see a dermatologist instead of trying only cosmetic products?
If hair loss is sudden or severe, bald patches appear, the scalp is inflamed, shedding persists for several months, or you suspect a hormonal, nutritional or genetic cause, a dermatological diagnosis is the first step.
