FAQ

Pre-Existing Conditions & Sensitive Situations

Can the 8T3 Essentials Hair Serum be used for seborrhoeic dermatitis?
Yes. No specific clinical trials have been conducted for this condition, but the serum can generally be applied for all types of hair loss. Consulting a doctor beforehand is recommended.
Is the 8T3 Essentials Hair Serum suitable for people with thyroid disorders or Hashimoto's disease?
Theoretically, yes. The experts recommend speaking with a doctor first and deciding together whether the product is appropriate.
Is there any experience with the 8T3 Essentials Hair Serum and multiple sclerosis?
No practical experience exists yet. Theoretically, there is no reason patients with MS should not use the product. 8T3 has no systemic availability and works locally, which makes combination with other conditions generally feasible. Consulting a doctor is still recommended.

No practical experience exists yet. Theoretically, the product could be used. The recommendation is to consult a doctor and decide together.

Description

The 8T3 Essentials Hair Serum can generally be used for all types of hair loss. No clinical trials for specific pre-existing conditions have been conducted yet. 

One relevant factor: 8T3 has no systemic availability. The active ingredient works locally and does not enter the bloodstream. That makes it relatively easy to combine with other conditions or ongoing treatments. 

For conditions such as thyroid disorders, Hashimoto's, multiple sclerosis, or lichen planopilaris, the experts consider application theoretically possible. No practical experience exists yet for any of these. In every specific case, they recommend speaking with a doctor first and making the decision together.
