Men's Scalp Serum with Baicapil, Caffeine & Peptides

$48.00

Built for men noticing early changes

The Daily Scalp Serum is designed to improve the appearance of thinner-looking hair while nourishing a scalp that feels dry or tight. Every active ingredient is disclosed at its actual concentration, so you know exactly what you're getting.

Baicapil at 4% is used at the level its manufacturer studied. This three-plant complex, derived from Scutellaria root, wheat germ, and soybean germ, was shown in the manufacturer's studies to visibly improve the look of scalp density and give hair a thicker appearance.

The 2% Peptide Hair and Scalp Complex with Hexapeptide-11 is a concentrated blend of peptides and botanical extracts (including green tea and naturally derived exfoliating acids from sugar cane, lemon, and apple) that helps hair look visibly stronger and fuller.

Caffeine at 1% is encapsulated in phospholipid liposomes, a lightweight delivery format that spreads evenly and stays where you apply it.

Two probiotic ferments, Saccharomyces Ferment and Lactobacillus Ferment, work alongside niacinamide and a 2% Amino Acid Complex to soothe and hydrate the scalp, visibly reducing dryness for a balanced, comfortable feel. A comfortable-feeling scalp makes the daily routine easy to stick with.

Sodium Hyaluronate seals in hydration, leaving the scalp feeling nourished rather than stripped.

Non-greasy, easy addition to my current routine

The Mannered Manes Scalp Thickening Serum has been an easy addition to my nightly routine. What I love about this product is that it is non-greasy and stays exactly where you apply it, and you can massage it in to make sure it absorbs. I felt thicker, healthier hair over the last 90 days. It's been a game changer throughout my hair journey. I appreciate a company like Mannered Manes that creates products made with quality ingredients to help solve common hair issues. While the issues did not change overnight, it's about creating a routine to help you keep the hair you have. I have increased confidence in my hair again.

Your questions, answered

Curly Hair / Fine Texture

Scalp dryness and irritation may visibly improve within the first 2 to 4 weeks. Improvements in the appearance of hair density and thinning are generally noticed at 90 days with consistent daily use. Individual results may vary.

Yes. This is a drug-free cosmetic formula. It stacks cleanly with whatever else is in your routine. Consult your doctor if you have any concerns about your specific hair loss regimen.

No. The formula is designed to absorb into the scalp. Apply directly to the scalp, not the hair, and it won't affect your style.

Every active ingredient in this formula is clinically tested and listed with its exact concentration. No proprietary blends, no underdosed trend ingredients. You know what's in it, how much, and why it's there.

This formula is not designed to treat dandruff or seborrheic dermatitis. The probiotic ferments and amino acid complex support a balanced scalp environment and may help address the appearance of general dryness and flaking. If you're dealing with a diagnosed scalp condition, we'd recommend speaking with a dermatologist. This is a cosmetic product, not a treatment.

No added fragrance. What you're smelling is the formula itself. The natural scent of the active ingredients. Nothing added.

The alcohol in this formula evaporates almost instantly on contact. It keeps the serum lightweight and non-greasy, so it absorbs cleanly without weighing your hair down. This way, there is no sticky residue and no greasy buildup.
