SOLVEO Hair Care and Body Wash: A Buyer's Guide
SOLVEO is a Korean hair and body care brand that sells in 1000ml professional-size bottles. The 12+ products on skinsli span four categories: hair loss shampoos, keratin treatment formulas, scalp-targeted shampoos for oily or buildup-prone hair, and fragrance-forward options for daily use. There is also one body wash in the range. This guide walks through each group to help you match the right product to your hair and scalp needs.
What SOLVEO Makes and Why 1000ml
SOLVEO positions its products in the professional and salon-use size tier - all current in-stock items are 1000ml, which is roughly four to six times the size of a standard retail shampoo bottle. At that volume, the cost-per-wash is lower than travel or retail formats, and households or professionals who go through shampoo quickly avoid frequent reordering.
The range is Korean in origin and follows the Korean haircare tradition of separating scalp health from general conditioning - the product names specify their function clearly: "Hair Loss," "Keratin Treatment," "Oily Shampoo," "Deep Cleansing." This makes it straightforward to identify which formula targets your specific scalp condition.
Hair Loss Shampoos: Black Peptide and Biom Beer Yeast
SOLVEO offers two hair loss-targeted shampoo formulas in 1000ml. The Black Peptide Hair Loss Shampoo uses peptides to support scalp health and strengthen hair at the follicle level. Peptides in topical haircare typically work by stimulating scalp circulation and providing amino acid building blocks that reinforce the hair shaft to reduce breakage and shedding.
The Biom Beer Yeast Hair Loss Shampoo uses fermented beer yeast as its key ingredient. Beer yeast contains B vitamins, biotin, zinc, and amino acids - all of which support the scalp microbiome and hair growth cycle. Fermented ingredients in Korean cosmetics are associated with improved ingredient absorption; beer yeast shampoos became popular in Korean haircare for their ability to add volume to fine, thinning hair while addressing the scalp.
Both formulas are for daily or frequent use, not intensive treatment masks. If your primary concern is shedding, either shampoo works as a consistent daily base. The Black Peptide suits those who prefer a modern active approach; the Beer Yeast suits those who respond well to fermented formulas.
Keratin Treatment and Keratin Shampoo: Extreme Line
The Extreme Keratin Treatment 1000ml is a leave-in or rinse-off treatment concentrate that deposits keratin proteins onto the hair shaft to repair damage, reduce frizz, and restore smoothness. It is the deepest conditioning product in the SOLVEO range and suited for chemically treated, heat-damaged, or color-processed hair that needs structural repair.
The Extreme Damage Keratin Shampoo 1000ml is the daily shampoo counterpart - it cleanses while depositing keratin on each wash, making it a maintenance companion to the treatment. Use the shampoo daily and the Keratin Treatment one to three times per week as a post-wash mask, left on for 5-10 minutes before rinsing. The 1000ml Keratin Treatment size gives approximately 30-60 application uses at standard amounts.
Tea Tree Cool Oily Shampoo for Scalp Sebum Control
The Tea Tree Cool Oily Shampoo 1000ml targets oily scalp conditions - excess sebum production, greasy roots, and scalp congestion. Tea tree oil is a well-established antibacterial and antifungal ingredient that reduces the microorganisms that contribute to dandruff and scalp odor, while its cooling effect (often from menthol in the formula) reduces the sensation of oiliness at the roots.
This shampoo suits people whose hair becomes visibly oily within 24 hours of washing. Apply it to a wet scalp, massage for 60-90 seconds to allow the tea tree actives to contact the scalp, then rinse thoroughly. It can be alternated with the Caffeine and Biotin Deep Cleansing Shampoo for a double-action anti-buildup routine.
Caffeine and Biotin Deep Cleansing Shampoo
The Caffeine and Biotin Deep Cleansing Shampoo 1000ml combines two scalp-focused actives. Caffeine stimulates scalp circulation and is associated with inhibiting the DHT pathway involved in some forms of hair thinning. Biotin (vitamin B7) is a cofactor in keratin production and is commonly found in hair loss supplements - in topical form, it supports the scalp environment. "Deep Cleansing" in the product name indicates a stronger clarifying action than a standard daily shampoo, making it suitable for removing product buildup, hard water deposits, and excess scalp sebum.
Use this shampoo two to three times per week rather than daily if your scalp is sensitive - the deep cleansing action can strip too much natural oil with daily use on drier scalp types. It works well as an alternating option alongside the Biom Beer Yeast or Black Peptide shampoo.
Signature Parfum Shampoos: White Mask and Baby Powder
SOLVEO's Signature Parfum Shampoo line brings fragrance-forward daily shampoos in 1000ml. The White Mask variant has a clean, musky, laundry-soap-type scent profile - similar to fabric softener or white musk perfume. The Baby Powder variant has a warm, soft, powder-like scent. Both are daily shampoos without a specific scalp treatment focus - they are chosen for their fragrance longevity on the hair.
Korean parfum shampoos have become popular in recent years for their ability to leave a detectable scent on the hair throughout the day, longer than standard shampoos. The 1000ml size makes them economical for daily use in households where fragrance is a priority. Neither variant contains strong actives for scalp conditions, so pair them with a targeted shampoo if you also have hair loss or oily scalp concerns.
Acne Clear Cool Body Wash 1000ml
The Acne Clear Cool Body Wash 1000ml is SOLVEO's single body care product in the current lineup. It targets body acne - breakouts on the back, chest, and shoulders - with a clarifying, cooling formula. Body acne typically involves follicular congestion and bacterial overgrowth; a targeted body wash with salicylic acid, tea tree, or similar actives helps reduce both. The "Cool" element in the name suggests menthol or a cooling agent for post-wash freshness.
Use it daily in the shower on breakout-prone areas, letting the formula sit on the skin for 30-60 seconds before rinsing for better active contact. The 1000ml format provides several months of daily use for the targeted body areas.
Building a Complete Hair Routine from SOLVEO
A complete SOLVEO routine for hair loss with scalp oiliness: alternate the Caffeine and Biotin Deep Cleansing Shampoo and the Black Peptide Hair Loss Shampoo on consecutive wash days. Once or twice per week, apply the Extreme Keratin Treatment as a post-wash mask for damage repair. If you want a fragrance element in your daily wash, use a Signature Parfum Shampoo on lighter hair days and rotate the actives-heavy shampoos on days when scalp treatment is the priority.
For oily scalp without significant hair loss, the Tea Tree Cool Oily Shampoo is the primary daily wash, with the Caffeine and Biotin Deep Cleansing version once a week for deeper clarification. The Extreme Damage Keratin Shampoo works as a daily conditioning shampoo if your hair is chemically treated or heat-damaged.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What products does SOLVEO make?
SOLVEO is a Korean brand that makes professional-size hair care and body care products. The 12+ items on skinsli include hair loss shampoos (Black Peptide and Beer Yeast), keratin treatment and keratin shampoos, scalp-targeted formulas (Tea Tree Cool Oily, Caffeine and Biotin Deep Cleansing), fragrance-forward Signature Parfum shampoos (White Mask and Baby Powder), and the Acne Clear Cool Body Wash. All current in-stock items are 1000ml.
Why are SOLVEO products sold in 1000ml bottles?
SOLVEO uses 1000ml professional-size bottles to lower the cost per wash and reduce how often you need to reorder. A 1000ml shampoo used daily by one person typically lasts 3-5 months. The format is common in Korean salon-grade haircare where larger sizes are used by hairdressers and by households that want a professional-volume supply at home.
What is the difference between the SOLVEO Black Peptide Hair Loss Shampoo and the Biom Beer Yeast Hair Loss Shampoo?
Both target hair thinning and shedding but use different key ingredients. The Black Peptide Hair Loss Shampoo uses peptides to reinforce the hair shaft and support follicle health at a structural level. The Biom Beer Yeast Hair Loss Shampoo uses fermented beer yeast - rich in biotin, B vitamins, and zinc - to nourish the scalp microbiome and add volume to fine hair. If you want a more science-backed active approach, choose the Black Peptide. If your hair is fine and you also want volume alongside anti-hair-loss support, the Beer Yeast tends to add more body.
How do I use the SOLVEO Extreme Keratin Treatment 1000ml?
Shampoo with the Extreme Damage Keratin Shampoo or another SOLVEO shampoo, then towel-dry slightly so hair is damp but not dripping. Apply the Extreme Keratin Treatment from mid-lengths to ends, working it through evenly. Leave on for 5-15 minutes depending on damage level, then rinse. Use one to three times per week for damaged or chemically treated hair. At 1000ml, you get roughly 30-60 treatment applications at standard amounts.
Will the SOLVEO Tea Tree Cool Oily Shampoo 1000ml help with dandruff?
Tea tree oil has antifungal and antibacterial properties that target Malassezia, the yeast associated with dandruff. The Tea Tree Cool Oily Shampoo is primarily formulated for oily scalp and sebum control, but its tea tree content typically helps reduce dandruff in the process. Massage it into the scalp for 60-90 seconds before rinsing to give the actives enough contact time to be effective.
How many times per week should I use the SOLVEO Caffeine and Biotin Deep Cleansing Shampoo?
Two to three times per week is the standard recommendation for a deep cleansing shampoo. Daily use can over-strip natural scalp oils on normal or dry scalp types. On other wash days, alternate with the Black Peptide or Beer Yeast Hair Loss Shampoo. If your scalp is very oily or you use a lot of styling products, daily use is tolerated better than for normal or dry scalp types.
What do the SOLVEO Signature Parfum Shampoos smell like, and how long does the scent last?
The Signature Parfum White Mask has a clean, fresh musk scent similar to white musk or fabric softener. The Baby Powder has a warm, soft, powdery scent. Korean parfum shampoos are formulated for scent persistence - the fragrance typically lasts 6-12 hours on the hair after washing. Both are available in 1000ml and work as straightforward daily shampoos without a specific active scalp function.
How do I use the SOLVEO Acne Clear Cool Body Wash 1000ml for back acne?
Apply the Acne Clear Cool Body Wash to wet skin on acne-prone areas - back, chest, and shoulders. Let it sit for 30-60 seconds before rinsing to give the active ingredients contact time with the skin, rather than rinsing immediately. Daily use is appropriate for active breakouts. The cooling sensation comes from the formula rather than the water temperature - it is most noticeable immediately after application.
Can I use the SOLVEO Tea Tree Cool Oily Shampoo and a hair loss shampoo at the same time?
Yes. Alternating them is a common approach: use the Tea Tree Cool Oily Shampoo on days when sebum buildup is the main issue, and the Black Peptide or Beer Yeast Hair Loss Shampoo on other wash days. You can also use the Caffeine and Biotin Deep Cleansing Shampoo once a week for extra clarification, giving you three rotating shampoos that target oily scalp and hair thinning simultaneously.
How many SOLVEO products are available on skinsli?
Skinsli stocks 12+ SOLVEO products, all in 1000ml professional sizes. The range covers hair loss shampoos, keratin treatments, scalp-targeted formulas, parfum shampoos, and a body wash. All are in stock and ship from Korea.
