LABO H Hair Care: a Buyer's Guide to the Full Lineup
LABO H is a Korean hair care brand that focuses almost entirely on hair loss relief and scalp health. Its 45+ products on skinsli cover shampoos in multiple sizes, leave-on strengthening essences, rinse-out clinical treatments, and bundled sets designed to run a complete routine without mixing brands. This guide walks through the range so you can pick the right entry point and build from there.
What LABO H Makes - and Why the Focus on Hair Loss
LABO H is not a general personal-care brand. Every product in the lineup is built around scalp health and hair-thinning concerns - from cooling shampoos that reduce scalp inflammation to high-concentration strengthening essences that you apply to the scalp and leave in. The brand argues that shedding is primarily a scalp problem, so it addresses the root rather than just coating the strand.
The 45+ products on skinsli include individual items at different sizes and multi-step sets. Whether you want a single-item trial or a full regimen kit, there is a SKU for it.
The Shampoo Range: Cooling vs Strengthening
Two shampoo lines anchor the LABO H range. The Hair Loss Relief Shampoo Scalp Cooling is available in 400 ml, 750 ml, and a 400 ml refill. The cooling variant uses ingredients that lower scalp temperature after washing - a factor the brand links to reduced inflammation and improved blood flow. The 750 ml bottle is the best value for daily use; the refill pouch trims cost on repeats.
The Scalp Strengthening Shampoo (also called the 9 Hair Loss Relief Shampoo, 337 ml) takes a different angle: it prioritizes strand-anchoring ingredients over the cooling sensation. If your main concern is breakage at the root rather than an itchy or inflamed scalp, this variant is the better fit.
Choosing the Right Size: 337 ml, 400 ml, 750 ml, or Refill
LABO H shampoos come in four packaging formats, which matters for ongoing use. The 337 ml bottle is a standard size and works well for a first purchase. The 400 ml is slightly larger and is also available as a standalone refill - if you already own the pump bottle, the refill pouch costs less per wash. The 750 ml is the large-format daily driver and the cheapest cost-per-use option across the line.
For the 1-month collection (labelled as "1 mouth collection of hair loss relief shampoo"), the sizing covers roughly one month of daily use for medium-length hair, which makes it a useful benchmark when comparing formats.
Hair Strengthening Essence: the 75 ml Leave-On Step
The 75 ml Hair Strengthening Essence is the leave-on scalp step in the LABO H routine. You apply it to a towel-dried scalp, massage it in, and skip the rinse. The bottle is small enough for travel and designed for precision application along the part line or thinning zones. Because it is not washed out, the active ingredients have longer contact time with the scalp than any shampoo provides.
This is typically the second step after shampoo - apply while the scalp is still slightly damp for better absorption. It pairs with either of the LABO H shampoos and with the Clinic Treatment.
Hair Strengthening Clinic Treatment: the 200 ml + 100 ml Duo
The Clinic Treatment comes as a 200 ml + 100 ml bundle, covering both a full-size and a travel or backup container. It is a rinse-out conditioner-style treatment that positions itself at a clinical intensity - heavier on conditioning agents than standard conditioners, with the same hair-loss-relief angle as the rest of the line.
Use it two to three times per week in place of a regular conditioner, or daily if your strands are very dry. The 200 ml is enough for approximately four to six weeks of regular use depending on hair length.
Sets: 4-Piece, 5-Set, and What Each Covers
LABO H sells two prominent bundle options on skinsli. The Premium Hair Care 4-piece set pairs a shampoo, the essence, and a treatment with a fourth supporting step. The 5 Special Hair Care set is a larger bundle that typically combines multiple product categories into one purchase. Both sets are cheaper per item than buying individually and remove the guesswork of which products work together - LABO H designed the sets as self-contained routines.
Sets are the best starting point if you have not used LABO H before and want to run the full routine without selecting each piece separately. They also make practical gifts because everything is already matched.
How to Build a LABO H Routine: Step Order
A standard LABO H routine runs three steps. First, the shampoo - work it into a wet scalp, massage for 60 to 90 seconds to activate the cooling or strengthening ingredients, then rinse thoroughly. Second, if using the Clinic Treatment, apply to mid-lengths and ends (not the scalp), leave for two to three minutes, then rinse. Third, towel-dry and apply the Strengthening Essence directly to the scalp before styling.
On lighter days you can skip the Clinic Treatment and just run shampoo plus essence. The essence is the step to keep consistent - it is where most of the leave-on actives are concentrated.
Who Gets the Most From LABO H
LABO H products suit anyone dealing with thinning, seasonal shedding, or an inflamed or irritated scalp. The cooling shampoos are particularly useful for oily or warm scalps that feel sensitive after washing. The strengthening variants are a better fit for drier scalps or hair that breaks at the root rather than shedding from the scalp. The leave-on essence is appropriate for all scalp types; the Clinic Treatment is best for those whose strands are also dry or chemically treated.
The range is not formulated for color protection or curl definition - it is a single-focus line. If hair loss or thinning is your primary concern, LABO H is a direct match. If you want a general moisturizing or smoothing routine alongside hair-loss care, pair a LABO H shampoo and essence with a separate deep conditioner for the lengths.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What is the difference between the LABO H Scalp Cooling shampoo and the Scalp Strengthening shampoo?
The Scalp Cooling shampoo prioritizes lowering scalp temperature and reducing inflammation after washing. It is a better fit for oily, itchy, or heat-sensitive scalps. The Scalp Strengthening Shampoo focuses on anchoring strands at the root with strengthening agents. If your main issue is breakage or hair that falls out with gentle pulling rather than an inflamed scalp, the strengthening version is the more targeted pick.
When should I buy the 400 ml LABO H shampoo refill instead of the full bottle?
Buy the refill once you already own the pump bottle from a previous purchase. The refill pouch has no dispenser of its own - you pour or squeeze it into your existing bottle. It is cheaper per ml than the full bottle and produces less packaging waste. If this is your first LABO H order, start with the 400 ml or 750 ml full bottle.
How do I apply the LABO H 75 ml Hair Strengthening Essence?
Apply the essence to a towel-dried scalp - not soaking wet, not fully dry. Part your hair to expose the scalp, dispense a small amount of the essence directly onto the scalp, and massage in with fingertips in small circles. Do not rinse. Use it after your shampoo (and after the Clinic Treatment if you are using that step) while the scalp is still slightly warm from washing, which helps absorption. Use daily or at minimum five days a week for consistent results.
How often should I use the LABO H Hair Strengthening Clinic Treatment?
Two to three times per week is the standard recommended frequency. Apply to the mid-lengths and ends after shampooing, leave for two to three minutes, then rinse thoroughly. If your hair is very dry or chemically treated - bleached, permed, or relaxed - you can use it every wash. The 200 ml bottle in the dual pack covers roughly four to six weeks at that frequency for shoulder-length hair.
Should I start with the LABO H 4-piece set or the 5 Special Hair Care sets?
The 4-piece Premium Hair Care set is the more common starting point - it covers the three core steps (shampoo, essence, treatment) plus a fourth supporting item. The 5 Special Hair Care sets is a larger bundle that provides more product in total and is suited if you want a longer supply upfront or want to share with someone else at home. If you are new to LABO H, the 4-piece set gives you a full routine trial without over-committing on quantity.
Is the LABO H 750 ml shampoo worth it over the 400 ml?
Yes, if you plan to use the shampoo daily. The 750 ml has the lowest cost-per-wash across all LABO H shampoo sizes and saves you from reordering as frequently. The 400 ml is a reasonable choice if you want to try the formula before buying a large bottle, or if you share a bathroom where a large shampoo takes up too much space. For households of two or more using LABO H daily, the 750 ml is the practical pick.
LABO H products say "hair loss relief" - are they for clinical hair loss or everyday shedding?
The LABO H lineup addresses both the everyday shedding that increases with stress, diet changes, or seasonal shifts, and the early-stage thinning that is visible at the part line or temples. They are over-the-counter cosmetic products, not medical treatments for conditions like androgenetic alopecia that require a dermatologist's prescription. If you are seeing significant bald patches or sudden rapid shedding, see a doctor in addition to using a scalp-focused routine.
What does "Scalp Cooling" mean in the LABO H shampoo name?
It refers to a cooling sensation produced by specific ingredients - menthol is the most common - that lower the perceived temperature of the scalp during and after washing. LABO H uses this as a proxy for reduced inflammation: a cooler scalp typically has reduced blood vessel dilation and less surface irritation. The cooling effect is noticeable for about 10 to 20 minutes after rinsing and is most appreciated in summer or by people who work out before washing their hair.
What is the LABO H "1 month collection of hair loss relief shampoo"?
It is a single-item or small bundle sized to cover approximately one month of daily use for average-length hair. LABO H uses this label to help you gauge how long the supply lasts before your next order. It is not a subscription - it is a one-time purchase. The amount is calibrated for daily shampooing; if you wash every other day, the same package stretches closer to two months.
Are LABO H products on skinsli genuine and shipped from Korea?
Yes. Skinsli sources LABO H directly and ships from Korea. Products arrive in original LABO H packaging with Korean labeling intact. Skinsli does not repackage or relabel items.
Can I use the LABO H Strengthening Essence alongside a separate scalp oil?
Yes, but apply the essence first while the scalp is still slightly damp, let it absorb for two to three minutes, then apply any scalp oil on top. Reversing the order - oil first, then essence - will block the essence from reaching the scalp. Keep oil amounts small on days you use the essence so neither product is diluted significantly.
What are the key active ingredients in LABO H hair loss relief products?
LABO H formulates with a combination of biotin, niacinamide (vitamin B3), and various plant extracts that are associated with scalp circulation and reduced DHT sensitivity at the follicle level. The cooling shampoos add menthol or similar cooling agents. Full ingredient lists are printed on each product box and available in product detail pages on skinsli.
