What Makes Etrivex Different?
Unlike conventional scalp treatments that require separate application steps or leave hair looking greasy, Etrivex is applied like a shampoo — making adherence much easier. Its active ingredient, clobetasol propionate 0.05%, is a very potent corticosteroid that works rapidly to reduce the inflammation, scaling, and itching characteristic of scalp psoriasis.
The 15-minute contact time is designed to allow adequate penetration of clobetasol into the scalp without requiring prolonged exposure. Once rinsed off, hair can be washed and styled normally — no residue, no odour, no disruption to your routine.
Clinical Benefits of Etrivex
- Rapid symptom relief — itching and redness typically reduce within 1–2 weeks
- Reduces scaling — clobetasol suppresses the accelerated skin cell turnover driving psoriatic plaques
- Convenient shampoo format — no need for separate scalp applications or greasy ointments
- Evidence-based — clobetasol propionate is the most studied topical corticosteroid in scalp psoriasis
- Suitable for moderate scalp psoriasis — where milder treatments have been insufficient
Step-by-Step: How to Use Etrivex Correctly
1
Part your hair on a dry scalp
Part and separate hair to expose affected scalp areas. Ensure the scalp is dry before application — applying to wet hair dilutes the medication.
2
Apply the shampoo
Apply approximately 7.5ml (around 1.5 teaspoons) directly to the dry scalp, massaging gently over all affected areas. Do not use more than prescribed.
3
Wash hands immediately
Wash hands thoroughly immediately after application to avoid transfer to eyes or other sensitive areas.
4
Leave on for 15 minutes
Do not cover the scalp with a shower cap or any material during this period. Allow the medication to work without occlusion.
5
Rinse thoroughly
After 15 minutes, rinse the shampoo off completely with water. You may follow with your regular shampoo if desired.
Important: Use once daily for a maximum of 4 weeks without clinical review. Do not use for more than 4 weeks without speaking to your prescriber. Prolonged use of potent corticosteroids carries risks including skin thinning and adrenal suppression.
Who Should Not Use Etrivex?
Etrivex is not appropriate for everyone. It should not be used if you have:
- A known allergy to clobetasol propionate or any other ingredient
- Active skin infections (bacterial, viral, fungal, or parasitic) on the scalp
- Open sores or ulcerative wounds on the scalp
- Rosacea, acne, or perioral dermatitis
Children under 2 years of age should not use Etrivex. Older children and adolescents require close monitoring under medical supervision. Discuss use during pregnancy or breastfeeding with your prescriber.
