Biotin beard shampoo: cleanse, strengthen and support fuller growth

Biotin is a B vitamin that supports stronger follicle activity and boosts natural beard growth. A beard shampoo built with biotin and castor oil cleanses without stripping the beard or the skin beneath, then nourishes and conditions every wash. SPARTAN BEARD™ Shampoo is a sulfate-free formula that lifts dirt and buildup while supporting thicker, fuller-looking facial hair over time.

What biotin does for beard growth

Biotin supports the strength of hair follicles at the root, helping them produce stronger, thicker strands. When you wash with biotin regularly, the vitamin works with castor oil to encourage fuller beard development over time. The effect builds wash after wash.

Most beard shampoos strip the beard with sulfates and leave nothing behind. SPARTAN BEARD™ Shampoo lifts dirt and excess oil without that damage, so biotin can do its job.

The ingredients that make it work

Biotin – supports stronger follicle activity and boosts natural beard growth.
Castor Oil – promotes thicker, fuller beard development over time.
Aloe Vera – soothes the skin and reduces itch, dryness and irritation.
Tea Tree Extract – helps prevent beardruff and keeps the skin beneath clean.
Coconut Oil – nourishes the beard and skin while reducing dryness.
Jojoba Oil – hydrates deeply and balances natural oils for healthy growth.
Argan Oil – adds shine, smoothness and strengthens beard hair.
Vitamin E – protects hair from breakage and supports overall beard health.

All sulfate-free, 99 per cent natural, no parabens or harsh chemicals.

How to wash for best results

Wet your beard thoroughly with warm water. Work a small amount of shampoo into your hands, then massage it deeply into the beard and the skin underneath. Leave it for thirty to sixty seconds to allow the biotin and oils to absorb. Rinse thoroughly and pat dry. Use three to five times weekly for the best results and a healthier, fuller beard.

Who this is for

Men growing or maintaining a beard and wanting thicker, fuller growth. Guys with dry, itchy or flaky skin who need relief from beardruff and irritation. Daily groomers who want a clean, natural product that does not strip the beard. Anyone who wants a sharper, more masculine appearance backed by science and nature.

What makes it different

Most beard shampoos clean and nothing else. SPARTAN BEARD™ Shampoo cleanses deeply, nourishes every strand, soothes the skin beneath the beard, and supports fuller growth through biotin and castor oil. The sulfate-free formula leaves your beard soft, hydrated and refreshed after every wash, with a luxury fragrance inspired by Bleu de Chanel.
