The Intensive Care Scalp Cooling Shampoo (400ml) is the core cleansing product in this line. It uses menthol cooling alongside a stronger hair loss prevention complex compared to the standard Scalp Cooling Shampoo. The formula is designed for daily washing - the cooling stimulation, daily contact time, and hair loss actives work together more effectively with frequent use than with a 2-3x per week approach.

For people stepping up from the standard Scalp Cooling Shampoo who want more potency, this is the direct upgrade path. The active difference is meaningful enough that most users notice a different scalp sensation and faster visual improvement in shedding reduction.

The Intensive Care Scalp Cooling Scrub Shampoo (200ml) adds physical exfoliation to the cooling formula. Scalp scrubs are underused in hair care - they remove dead skin cell buildup, excess product residue, and congested sebum plugs that block follicles and prevent shampoo actives from reaching the scalp surface. The scrub format makes it a once or twice weekly treatment rather than a daily shampoo.

The 200ml size is appropriate for periodic use rather than daily, as you'd use it less frequently than a standard shampoo. Use it before your regular shampoo on scrub days, or as a standalone cleanser when deeper removal is needed. Avoid daily use - over-exfoliation disrupts the scalp barrier.

The Multiperfection Intensive Care Conditioner (400ml) handles conditioning, scalp treatment, and strengthening in a single product. "Multiperfection" means you're getting the routine benefits of a separate leave-in or rinse-out treatment folded into a conditioner. It reduces the number of products needed on wash days and is particularly useful for people who consistently skip the conditioner step in favor of simpler routines.

It's a rinse-out conditioner: apply after shampooing, leave for 1-3 minutes, rinse thoroughly. At 400ml, it's well-matched to the 400ml Intensive Care shampoo - they run out at roughly the same rate for most users.

Two tonics sit in the Intensive Care lineup: the Multiperfection Intensive Care Scalp Tonic (150ml) and the Hair Loss Intensive Care Multiperfection Intensive Care Scalp Tonic (50ml). Both are leave-on treatments applied to the scalp after washing. The 150ml is the daily-use size; the 50ml is a concentrated or starter version. The Multiperfection naming means the tonic combines multiple treatment functions - scalp care, hair loss actives, and hydration - in a single product.

Apply to a clean, damp scalp in sections without rinsing. These tonics have the highest active contact time in the Intensive Care routine, making them a key step for people whose primary goal is hair loss prevention rather than just scalp condition management.

The Intensive Care Scalp Cooling Tonic (150ml) carries the same cooling/stimulation mechanism as the shampoo but in leave-on form - so the vasodilation and circulation-boosting effect lasts far longer than a rinse-off product can deliver. Applied after washing and left on throughout the day (or overnight), it provides continuous scalp stimulation that supports follicle health between wash sessions.

It's one of the more directly effective products in the Intensive Care line for people dealing with thinning related to poor scalp blood flow. Pair it with the Intensive Care Cooling Shampoo on the same wash days for maximum effect.

The Biotin Ampoule Treatment (250ml) is the most ingredient-focused product in the Intensive Care line. Biotin (vitamin B7) is one of the most studied nutrients for hair and nail health - a deficiency is directly linked to hair loss, though biotin topical application has uncertain absorption compared to oral supplementation. The ampoule format delivers a high concentration of biotin and supporting actives, applied as a treatment (rinse-out or leave-in depending on the specific product instructions) rather than a daily shampoo.

At 250ml, this is a generous size for a treatment product. It's suitable for people who want a topical biotin application in addition to any oral supplementation, or for those who prefer topical approaches. Results are most visible for biotin-deficiency-related hair loss, and take 6-8 weeks of consistent use to assess.

The Beer Yeast Intensive Care Shampoo (688ml) is one of Dr.Groot's more distinctive products. Beer yeast (Saccharomyces cerevisiae) is rich in B vitamins, amino acids, and minerals - nutrients that directly support scalp health and hair fiber strength. Fermented ingredients in skincare and hair care are a well-established trend in Korean beauty, with fermentation increasing bioavailability and adding beneficial metabolites to the base ingredient.

The 688ml is an unusually large size - close to 700ml - and is clearly designed for daily use as a primary shampoo. The formula combines the yeast nutrition complex with the broader Intensive Care active profile for a shampoo that feeds the scalp while treating hair loss. It's a practical pick for people who want nutritional actives in their cleanser without adding a separate supplement step.

The Multiperfection Intensive Care lineup includes two targeted variants: the formula for Itchy Scalp (400ml) and the formula for Oily Scalp (400ml). These are conditioner-like products ("Talmomampu" suggests a treatment rinse-out format in Korean) that combine intensive care with condition-specific actives. The Itchy Scalp version adds calming, anti-itch actives; the Oily Scalp version adds sebum regulation alongside the intensive care profile.

These fill the gap between a general conditioner and a targeted treatment - useful for people who need both the conditioning step and a specific scalp condition addressed simultaneously.

The Intensive Care line is appropriate when standard Density Care or base Scalp products haven't produced sufficient results after 6-8 weeks, or when hair loss is noticeably pronounced from the start. If you're just beginning a hair loss prevention routine and loss is mild or precautionary, starting with the Density Care Shampoo is a more conservative approach. The Intensive Care products are stronger and more complex - worth the higher potency if the situation warrants it, but not necessary for every user.
