Alastin

ALASTIN sits in the salon-grade end of Korean haircare. The focus across the range is moisture repair rather than styling, which shows in product names like Moisturizing Shampoo, Moisture Treatment, and Phytokeratin Moisture Treatment. It suits hair that feels rough, brittle, or thirsty after bleaching, perming, or repeated colouring.

Because the same formulas come in both small home bottles and large salon containers, the brand works for an individual restocking a shelf and for a stylist buying for the backwash. If you are new to it, the moisturizing shampoo plus one treatment is the natural starting pair.

The cleansing side of the range is the Moisturizing Shampoo and the Moisturizing Rinse. The shampoo comes in a 50ml trial size, a 1L bottle for regular use, and larger formats for salons, so you can test it before committing to a big container. The rinse runs up to 2100ml, which is a salon-volume product meant for repeated use through the day.

This is a hydrating cleanse rather than a deep-clarifying one, so it pairs well with the treatments below without stripping them straight back out. For most people the shampoo is the everyday workhorse and the rinse follows it in the same wash.

The Phytokeratin Moisture Treatment is one of the headline repair products and comes in 200ml and 300ml. Keratin is the protein hair is made of, and a phytokeratin (plant-derived) treatment is aimed at smoothing and reinforcing strands that have lost structure to heat or chemicals. The Silkripair Signature Treatment 300ml sits in the same repair tier for hair that needs a richer rebuild.

Use a treatment after shampooing, on the mid-lengths and ends rather than the scalp. Leave it to sit for a few minutes so it can absorb, then rinse. These are the products doing the heavy lifting on damage.

Alongside the keratin line, the brand carries the Propolitera Treatment 300ml and a plain Moisture Treatment 200ml. Propolis is a bee-derived ingredient used in Korean care for its soothing and conditioning feel, so the Propolitera option leans toward comfort and softness as much as repair.

The Moisture Treatment is the simpler hydrating mask of the set, a good choice when hair is dry but not heavily damaged. Between the keratin, propolis, and plain moisture treatments you can match the intensity of the treatment to how stressed your hair actually is.

ALASTIN also covers colour through its Salon Color range, including a 100g format and dyeing products. These are professional colour items, so they fit a stylist's kit more than a casual home user. If you colour at the salon, keeping the brand's own colour and aftercare together means the moisture treatments are tuned for the same hair you have just processed.

If you are buying purely for at-home care, you can skip the colour items and stay with the cleansing and treatment products. The colour line is here for completeness and for professionals working in the brand.

One of the practical strengths of this range is the spread of sizes. A 50ml shampoo is a true travel and trial size, the 200ml and 300ml treatments are home-bathroom sizes, and the 1L shampoo and 2100ml rinse are salon volumes for heavy use. Buying the small size first lets you confirm a product suits your hair before you move up to a bulk bottle.

For value, the larger formats bring the per-use cost down, which is why salons buy them. Match the size to how often you will reach for the product rather than buying the biggest container by default.

A simple ALASTIN routine is shampoo, then rinse, then a treatment once or twice a week depending on damage. Put the treatment on damp hair after cleansing, concentrate it on the lengths, and give it a few minutes before rinsing. Heavily bleached or processed hair can take a treatment more often; healthy hair needs it less.

Because the cleansing and repair steps are designed around the same moisture goal, they stack cleanly without fighting each other. Start light and add treatment frequency only if your ends still feel dry.

ALASTIN is a Korean brand, and we carry its range so you can buy it without sourcing salon stock yourself. We currently list 180+ ALASTIN products in stock, which covers the cleansing, treatment, and colour lines rather than a single hero item.

That depth matters for a salon brand, because the treatments are meant to be used as a system. Having the shampoo, rinse, and matching treatments available together is what lets you run the full routine the brand was designed around.
