H Bloom AHL with HALOS

Price range: £23.25 through £155.00 VAT excl.
(£27.90 – £186.00 VAT incl.)

H Bloom AHL is an advanced revitalising complex from Koru Pharma, built on proprietary KORU-AHL peptides and the HALOS multi-pathway system with Type XVII collagen, biotin and dexpanthenol.

Hair thinning has more than one cause, so H Bloom AHL works across five pathways at once, for fuller, denser and more resilient hair.

Five Pathways, One System

H Bloom AHL is an advanced revitalising complex from Koru Pharma, built on proprietary KORU-AHL peptides and the HALOS system for scalp balance and hair resilience.

Hair thinning rarely has one cause. Growth signals fall out of balance, the growth phase shortens, the scalp dries or turns oily, circulation drops and follicles lose their anchoring. HALOS is built to work on all five of those at once, rather than picking off a single one and hoping the rest follow.

Key Ingredients

The HALOS System

HALOS names the five pathways the formula works across: Hair follicle regulation, Anagen phase support, Lipid balance, Oxygenation and microcirculation, and Structural follicle support. Each ingredient in H Bloom AHL maps onto one or more of them, so the actives cover the whole picture rather than overlapping on a single mechanism.

KORU-AHL 01 & 02 Peptides

Koru Pharma’s proprietary peptides, and the heart of the formula. They are designed to act on BMP signalling, the natural messengers that regulate the hair growth cycle. When BMP activity runs high, follicle activity drops and growth slows. These peptides are designed to help bring that signalling back into balance, which is associated with improved density and reduced shedding.

Type XVII Collagen

A specific collagen found where the follicle anchors into the scalp, and closely tied to how securely hair is held in place. It supports follicle anchoring and the surrounding structure, helping reinforce the fibre against fragility and breakage, and works alongside the peptides to support a longer growth phase.

Biotin

Vitamin B7, working here on two fronts. It helps regulate sebum so the scalp sits neither greasy nor stripped, which matters for a scalp prone to dandruff or excess oil, and it contributes to keratin formation, the protein hair is actually built from.

Dexpanthenol

Provitamin B5, included for the scalp environment itself. It supports hydration and helps improve microcirculation, which in turn supports the delivery of oxygen and nutrients to the follicle. A better supplied scalp is a better place for hair to grow from.

Why H Bloom AHL?

Five Pathways, Not One

Thinning hair is rarely one problem. HALOS works across growth signalling, the growth phase, scalp balance, circulation and follicle structure together, so the formula matches the way thinning actually happens.

Rebalancing The Growth Signal

The KORU-AHL peptides target BMP signalling, the mechanism that regulates the hair cycle itself. Rather than only feeding the scalp, this aims at the switch that decides whether a follicle stays active.

Clinically Measured

A clinical study of 21 participants at the Korea Dermatology Research Institute measured a 15% increase in internal hair density and a 40% improvement in scalp microcirculation over 4 weeks, both statistically significant.

A Full Course In One Box

Eight 3ml vials per box, so a complete course arrives in a single purchase rather than being pieced together, with the cost per vial working out lower than buying singly.

Frequently Asked Questions

H Bloom AHL is a professional hair and scalp booster from Koru Pharma, described by the manufacturer as an advanced revitalising complex for scalp balance and hair resilience. It pairs proprietary KORU-AHL peptides with Type XVII collagen, biotin and dexpanthenol, and comes as a box of 8 x 3ml vials.

HALOS is Koru Pharma’s name for the five pathways the formula targets, and the letters spell them out: Hair follicle regulation, Anagen phase (the growth phase), Lipid balance, Oxygenation and microcirculation, and Structural follicle support. The point is that thinning has several drivers at once, so the formula is built to work on all five rather than a single one.

They are Koru Pharma’s own peptides, developed for this formula. They act on BMP signalling, the body’s natural messengers for regulating the hair growth cycle. When BMP activity is overactive, follicle activity falls and growth slows. The peptides are designed to help rebalance that signalling so follicles can function normally, which is associated with better density and less shedding.

It is a collagen concentrated at the point where the hair follicle anchors into the scalp, and it is strongly linked to how well hair stays put. Supporting it helps reinforce follicle anchoring and the surrounding structure, which is associated with less fragility, less breakage and more resilient hair.

The active complex is KORU-AHL 01 and 02 peptides, Type XVII Collagen, Biotin and Dexpanthenol. Each maps onto one or more of the five HALOS pathways, so the ingredients complement each other rather than doubling up.

Visible thinning and reduced density, increased shedding, and weak or fragile hair prone to breakage. It also suits scalps that are dry or dehydrated, dandruff-prone, producing excess sebum, or sensitive and easily irritated.

They are different generations of the same Koru Pharma hair line and suit different needs. H Bloom Booster is built on hyaluronic acid with a four peptide complex and is CE marked. H Bloom AHL is the newer HALOS formulation, built on the proprietary KORU-AHL peptides with Type XVII collagen, and comes as 8 x 3ml rather than 2 x 1ml.

Yes. A 4-week clinical study of 21 participants at the Korea Dermatology Research Institute measured a 15% increase in internal hair density using confocal laser scanning microscopy, and a 40% improvement in scalp microcirculation, both statistically significant. Separate laboratory testing also showed reduced BMP-related signalling activity, reduced collagenase activity and improved cell viability.
