The Serum · by STRND Hair
STRND Hair Serum
$89.00 one-time
The formula
Rosemary, castor and lavender oils, with cold-pressed argan, coconut, baobab, avocado and jojoba — plus vitamin E and biotin. Ten actives, nothing to hide behind.
How to use
Three drops to the scalp. Massage for thirty seconds. Three times a week — consistently. Style as usual; the serum wears invisibly.
What to expect, and when
Shine and scalp comfort in the first weeks. Early signs of density around weeks 8–12. In clinical research on rosemary oil, hair-count change was measured at six months of consistent use. Individual results vary.
Shipping & dispatch
Dispatched from Australia within 1–2 business days. Free tracked shipping on orders A$75 and over; a flat A$8.95 applies below that.
Returns & guarantee
Unopened product can be returned within 30 days of delivery for a full refund. If you have used the serum consistently for 90 days and seen nothing, write to us — we would rather make it right than keep the money.
What is inside
Ten actives, named.
No proprietary blends, no undisclosed complexes. Here is the whole list, and what each one is doing.
Rosemary oil
The anchor. Clinically studied for hair count; supports circulation in the scalp's smallest vessels.
Castor oil
A conditioning oil — coats and softens the strand, adds weight and shine.
Lavender oil
Calms the scalp and carries the scent. Chosen for comfort in a leave-in formula.
Argan oil
Cold-pressed. Rich in vitamin E and fatty acids; smooths the cuticle.
Coconut oil
Lauric acid penetrates the hair shaft and helps reduce protein loss.
Baobab oil
Light, fast-absorbing moisture for a scalp that runs dry.
Avocado oil
Deeply conditioning; helps soften brittle, breakage-prone lengths.
Jojoba oil
Closest to the scalp's own sebum — balances without heaviness.
Vitamin E
Antioxidant. Protects the oils in the bottle and the scalp on the head.
Biotin
A conditioning agent in topical form, supporting the feel and condition of hair.
Free from sulphates, parabens and silicones. Vegan, cruelty-free and colour-safe. Formulated and filled in small batches in Australia.
The object
Design is in the detail.
No detail is overlooked.
