Welcome to our hair serums section, where we stock a variety of curated serums to address a wide range of hair types and concerns. Whether you’re looking for a hair growth serum, a hair serum for frizzy hair or a serum to combat damaged tresses, we stock it all here at AllHair.ie! Read More

Incorporating a hair serum into your routine is vital for nurturing both the health and appearance of your hair. Using a serum can aid with hydration, frizz control, detangling and so much more.

If you’re looking for a hair growth serum, we offer a diverse selection formulated with powerful ingredients to stimulate hair follicles and promote healthy growth. Check out the Act Acre Stem Cell Serum 65ml, which nourishes the scalp and encourages hair regeneration, resulting in stronger strands.

We also recommend the The Ordinary Multi-Peptide Serum for Hair Density 60ml, a peptide-based serum which targets multiple factors that contribute to hair loss, helping you achieve thicker, denser-looking locks.

Combat hair loss with the advanced Nioxin Anti-Hairloss Serum 70ml. Enriched with powerful botanicals and antioxidants, this serum strengthens hair follicles and reduces breakage.

If your hair is feeling the effects of damage and breakage, our selection of repairing serums is here to help. Infused with nourishing ingredients, these serums work to repair and protect your hair.

Olaplex No. 9 Bond Serum 90ml is a bond-building serum formulated with patented technology to repair and strengthen damaged hair. You may also like the Kérastase Resistance Thérapiste Serum 30ml, designed to transform brittle, damaged hair. It’s designed for extremely damaged hair, helping to seal split ends and protect against further damage.

If you’re suffering from dandruff, our anti-dandruff serums are specially formulated to eradicate flakes and soothe irritated scalps. Kérastase Symbiose Intensive Anti-Dandruff Cellular Night Serum 90ml is a targeted overnight serum enriched with potent anti-fungal agents to purify the scalp and regulate sebum production.
