Pete & Pedro BOOST Hair & Beard Growth Serum – Fuel Hair Growth, Fortify Every Strand, & Fix That Patchy Beard

Pete & Pedro BOOST is our powerhouse growth serum that supercharges hair and beard growth with a potent blend of Biotin, Rosemary Oil, and over 20 essential oils. BOOST strengthens every strand, hydrates like a beast, and nourishes the scalp and skin beneath — delivering thicker, stronger, healthier hair and beard where you need it most.

Whether you're tackling thinning hair, shedding, slow growth, or a patchy beard that just won’t fill in, BOOST delivers a knockout punch of results without the junk. Made with 99.5% natural ingredients and zero parabens, sulfates, or silicones, this lightweight oil absorbs fast, smells fresh, and leaves no greasy residue. Just clean, potent performance that works day in and day out.

Perfect for all hair types, styles, and beard lengths. Use it consistently, and the results speak for themselves. Just remember: a little goes a long way. This stuff is powerful — 2-3 drops is all you need.

KEY TIP: BOOST is an oil! We can't stress this enough - you only need to use 2-3 drops. Max. Do not fill up the whole doppler and apply as it is a potent formula and the oil has to absorb into the skin. Less is more. Beards you get a bit more leeway but start small for both!

A: BOOST strengthens and nourishes hair and beard with a concentrated blend of natural oils. It promotes growth, hydrates deeply, and helps fill in thinning or patchy areas.

Q: Can I use BOOST on my beard?
A: 100%. BOOST is beard-approved — it softens, hydrates, and promotes fuller, healthier growth while calming irritated skin beneath.

Q: How much should I use?
A: Only 2–3 drops. It’s an oil — don’t overdo it. Start small and let it absorb fully. For beards, you can use a little more if needed.

Q: Will it make my hair or beard greasy?
A: Nope. BOOST is fast-absorbing and lightweight. When used as directed, it leaves zero greasiness behind — just smooth, hydrated strands.

Q: When will I see results?
A: Most see improvement in 2–3 months with consistent daily use. Some see results sooner. Stick with it — hair growth takes time and consistency.

A: For sure. BOOST is unisex and works great for anyone struggling with thinning hair, slow growth, or dryness.

Q: Can I use BOOST with other hair products or stylers?
A: Yes. Apply BOOST as a leave-in treatment first, then layer your favorite styling product after it absorbs.

Q: Should I rinse BOOST out?
A: No. BOOST is a leave-in formula. Let it absorb and do its thing — no rinse needed.
