How long does an anti-hair loss treatment last: 90 days or 180 days?
Posted by Roxana Dirlau
If you have noticed that your hair is shedding more than usual and have started an anti-hair loss serum, the first question that arises is natural: how long should I continue? Three months seem like a reasonable horizon, but clinical studies and dermatological practice show that results accumulate over time and that duration matters. In this article, we analyze what a 90-day treatment versus a 180-day one means in practice, and how to choose the right interval based on your type of hair loss.
In short, you will learn:
•what type of condition you have: telogen effluvium or androgenic alopecia
•what the difference is between a 90-day and a 180-day treatment course
•how to apply the serum correctly to achieve real results
•when it has the best results and the benefits of a lightweight texture
What type of condition do you have: telogen effluvium or androgenic alopecia (AGA)?
Before determining the optimal duration of treatment, it is essential to understand the mechanism behind hair loss. There are two forms frequently encountered in dermatological practice, with distinct pathophysiology.
Telogen effluvium represents diffuse shedding triggered by an identifiable factor: severe stress, childbirth, prolonged fever, or nutritional deficiency. Hair strands are lost uniformly across the entire scalp, a few months after the triggering event, due to the synchronization of a large number of follicles in the telogen phase.
Androgenic alopecia (AGA) is determined by the increased sensitivity of hair follicles to dihydrotestosterone (DHT). The hair strand progressively thins, with follicular miniaturization, following a characteristic topographic pattern.
In women (FAGA), thinning is diffuse at the vertex, while preserving the frontal line; in men (MAGA), the process begins bitemporally and progresses towards the vertex.
If you are unsure about the type of condition, if hair loss occurs without an obvious trigger, or if it persists for more than 6 months, a dermatological consultation is the recommended step. A correct clinical diagnosis, established through trichoscopic examination and anamnesis, guides both the choice of treatment and the optimal duration of the course.
What the 2026 study says about ivaHair Strong Hair Serum (in short)
The efficacy of ivaHair Strong Hair Serum was evaluated in a monocentric clinical study conducted in 2026, coordinated by Dr. Irinel Nedelcu, Primary Physician, in collaboration with the Ivatherm Research and Development Department. The cohort included 20 participants, 15 women and 5 men, aged between 18 and 79, diagnosed with non-scarring diffuse alopecia.
Efficacy was quantified using TrichoScan®, complemented by standardized photographic documentation and clinical dermatological examination. After 6 months of continuous application, results were significant: hair density increased by 35%, and hair thickness by 42%.*
7 active ingredients, 7 mechanisms of action against hair loss
Activates dormant hair follicles, transitioning them from the telogen phase to the anagen phase by stimulating cellular autophagy

Nourishes, strengthens, and reinforces hair anchoring
Protects against external aggressions
Hydrates and prevents hair breakage
Fortifies and imparts elasticity, resistance, and shine
Soothes and protects the scalp
*Monocentric clinical study, 6 months (June 2025–February 2026), 20 subjects (15 women, 5 men), 18–79 years old, with androgenic alopecia and telogen effluvium. Evaluation via TrichoScan®, standardized photographic documentation, and clinical examination. Primary Physician Dr. Irinel Nedelcu and Ivatherm Research and Development Department, Bucharest, 2026.
90 days vs 180 days: what it means in practice
To evaluate the impact of treatment duration, study participants were divided into two groups. The first group applied the serum for 90 days, after which they discontinued use. The second group maintained continuous application for 180 days.
Data obtained with ivaHair Strong Hair Serum shows that after 3 months of continuous application, the first results become visible: hair density increased by 12%, and hair thickness by 8%. After 6 months of continuous application, the magnitude of the benefits increased significantly, with density reaching 35% and hair thickness 42%.
The study also highlighted a persistent effect: the benefits were maintained for a period after stopping application. Therefore, it is recommended that the hair loss treatment protocol be repeated in cycles of at least 3 months, several times a year, to maintain results.
How to apply ivaHAIR Strong Hair Serum correctly to see a real change
Results in the study were achieved by following a rigorous home protocol. Apply 2 pipettes daily to a freshly washed scalp, gently patted dry with a towel. The serum should be applied directly to the scalp, not the hair length, and massaged gently for about one minute to stimulate local microcirculation and promote the absorption of active ingredients. Do not rinse the serum.
A few common errors decrease treatment effectiveness. Applying it to an unwashed scalp reduces absorption, as excess sebum and cosmetic residues block the penetration of active ingredients. Neglecting application days interrupts the rhythm of follicular stimulation. Abandoning the course after 3–4 weeks does not allow sufficient time to observe real clinical changes; the hair follicle has its own biological cycle, with results visible in months, not days.
When does ivaHAIR Strong Hair serum provide the best results?
Response to treatment is influenced by the underlying diagnosis. In the 2026 clinical study, the best results were recorded in cases of telogen effluvium and female androgenic alopecia (FAGA).
In male androgenic alopecia (MAGA), the serum can be integrated into a complex therapeutic protocol, in combination with anti-DHT therapies indicated by a specialist physician. The treatment plan is personalized during a dermatological consultation.
The benefits of an easy-to-use formula
The efficacy of a topical treatment depends directly on adherence to the protocol, i.e., the ability to follow it daily for months on end. Texture plays a key role in this equation. ivaHair Strong Hair Serum has an aqueous formula that absorbs quickly, leaves no residue, and does not make the scalp greasy.
During the 6 months of the study, no adverse reactions were reported. Participants' scalps remained hydrated, with a visible reduction in flaking. A well-tolerated formula that is easy to integrate into a daily routine is the premise for consistent application, which is the only way to achieve relevant clinical results.
Frequently Asked Questions
According to data from the 2026 Ivatherm clinical study, the first visible results of using ivaHair Strong Hair Serum appear after 3 months of continuous application. At 6 months, both hair density and strand diameter show significantly higher increases compared to initial values.
Telogen effluvium begins suddenly and diffusely, a few months after an identifiable trigger. Androgenic alopecia sets in progressively, with gradual thinning and follicular miniaturization, following a specific topographic pattern. A definitive diagnosis is established during a dermatological consultation, through trichoscopy and personalized clinical examination.
The acute form of telogen effluvium is self-limiting—it resolves spontaneously, usually within a few months of the disappearance of the trigger. In case the shedding persists for more than 6 months, the situation takes on the characteristics of chronic telogen effluvium and requires dermatological evaluation to rule out underlying causes.
Yes, during the 6 months of the study, no adverse reactions were recorded, and participants' scalp flaking was reduced. The formula is well-tolerated on sensitive scalps. However, it is recommended to avoid application on scalps with active lesions or severe inflammation.
No, the serum has an aqueous texture that absorbs quickly, leaving no greasy feeling and not affecting the look of the hair after application. Seborrheic tolerance was good in all cases during the study.
The protocol requires 2 pipettes per day, applied to a freshly washed scalp that has been gently patted (not rubbed) with a towel—slightly damp. The serum should be distributed directly onto the scalp, not the hair length, and should not be rinsed off.
The main errors that compromise the effectiveness of the treatment are: applying it to an unwashed scalp (sebum and residue reduce absorption), not applying it daily, and abandoning the treatment prematurely, after only a few weeks. The hair follicle responds to continuous and consistent stimulation on a clean scalp.
Yes, for male androgenetic alopecia, ivaHair Strong Hair Serum can be integrated into a protocol that includes systemic or topical anti-DHT therapies as indicated by a specialist physician. The therapeutic combination is decided during a dermatological consultation, depending on the severity of the condition and the patient's profile.
Yes, for additional nutritional support, the serum can be combined with Keratine 1000 Biotine, a formula that provides biotin and keratinizers essential for the hair shaft. The recommended dose is 2 capsules per day, after a meal.
The clinical study highlighted a persistent effect: the benefits obtained were maintained for a period after the application was stopped, suggesting a sustained modulation of follicular activity. To maintain results over the long term, the protocol is recommended to be repeated in cycles of at least 3 months, several times a year, depending on the type of hair loss. The optimal duration of the treatment is not a universal value, but a decision adapted to the cause and the therapeutic goal. Three months marks the first evaluable stage; six months consolidate and amplify the results.
