Baxter of California Deep Clean Shampoo (473ml)

Some washes just don't cut it - and when product buildup, excess oil, and scalp congestion have accumulated over days, your regular shampoo isn't always going to shift it. The Baxter of California Deep Clean Shampoo is built for exactly that job: a purifying, clarifying shampoo that goes deeper than a daily wash to remove stubborn buildup from both the scalp and hair without stripping them dry in the process. Apple cider vinegar is the hero ingredient here - a well-established clarifying agent that dissolves product residue, restores the scalp's natural pH balance, and brings back the shine that buildup consistently dulls. Menthol provides an invigorating, cooling sensation on the scalp that makes the clean feel as thorough as it actually is. Ginseng root extract tones and stimulates, and sage leaf extract adds a botanical balancing element to the formula. The result is hair that feels genuinely reset - lighter, cleaner, and more alive than a standard wash delivers. Use it once or twice a week alongside your regular daily shampoo to keep buildup from ever getting ahead of you.

Who's It For

Built for anyone whose scalp or hair accumulates buildup faster than a daily shampoo can manage - equally effective as a weekly reset for any hair type. A strong fit for:

• Guys who use styling products regularly - pomade, wax, clay, paste - and need a shampoo that actually clears the residue
• Anyone with an oily scalp where sebum and buildup accumulate quickly between washes
• Those whose hair looks dull, flat, or weighed down despite regular washing - often a sign of product and mineral buildup
• Anyone returning from travel, extended outdoor activity, or a period of heavier product use who needs a proper reset
• Works well as a once or twice weekly complement to the Fortifying or Daily Complete Care systems - use it in place of your regular shampoo on reset days 

Key Benefits

• Apple cider vinegar clarifies and purifies the scalp and hair - dissolving product buildup, excess oil, and mineral deposits that dull the hair
• Restores the scalp's natural pH balance - disrupted by product buildup and hard water over time
• Brings back natural shine and vibrancy to hair that looks flat or lacklustre from accumulated residue
• Menthol delivers an invigorating, cooling sensation that stimulates the scalp and confirms the deep clean is happening
• Ginseng root extract (Panax Ginseng) tones and stimulates the scalp, supporting a healthy follicle environment
• Sage leaf extract (Salvia Officinalis) balances the scalp and adds a botanical toning element to the cleanse
• Removes stubborn styling product residue that regular shampoos leave behind - particularly effective for wax and pomade users
• Sulfate-free formula clarifies effectively without over-stripping or leaving the scalp dry or reactive
• Glycerin maintains baseline moisture during the deeper cleanse so hair doesn't feel stripped after rinsing
• 473ml - a generous size that lasts well when used as a weekly treatment rather than daily

Key Ingredients

• Apple Cider Vinegar (Acetum / Vinegar) - The clarifying hero of this formula. Apple cider vinegar dissolves product buildup, removes mineral deposits from hard water, and restores the scalp's natural acid mantle - bringing back shine and balance that regular shampoos can't deliver on their own. A well-established natural clarifier with a track record that genuinely holds up.
• Menthol - Provides an immediate, cooling sensation that stimulates blood circulation in the scalp and gives a tangible sense of deep cleansing happening at the roots. More than just a sensory effect - scalp stimulation supports a healthier follicle environment over time.
• Panax Ginseng Root Extract - A well-researched botanical tonic that stimulates the scalp, improves circulation around the follicle, and contributes to the overall revitalising effect of the deep clean formula.
• Sage Leaf Extract (Salvia Officinalis) - A botanical with natural astringent and balancing properties that tones the scalp during cleansing - particularly effective for oily scalps where excess sebum production is a contributing factor to buildup.
• Glycerin - A humectant that maintains moisture in the hair and scalp during the deeper cleansing process - preventing the dryness or tightness that some clarifying shampoos cause by over-stripping. 

How To Use

Wet hair thoroughly with warm water. Apply a generous amount to the scalp and work through to the ends. Massage firmly into the scalp for at least 60 to 90 seconds - the apple cider vinegar and clarifying agents need contact time to dissolve buildup properly. Leave on for an additional minute if buildup is significant before rinsing. Rinse thoroughly with warm water, then finish with a cool rinse to seal the cuticle. Follow with your regular conditioner - the Fortifying Conditioner or Daily Complete Care Conditioner both work well after a deep clean wash. Use once or twice per week on reset days, alternating with your regular daily shampoo. Note: More frequent use than twice weekly is not recommended - the deeper cleansing action is designed for periodic use, not daily replacement of your regular shampoo.

Why MASC Recommends This

The Deep Clean Shampoo fills a gap that most hair routines have but don't realise - the periodic reset that clears what daily washing leaves behind. Styling product users in particular will notice the difference immediately: the first time you use a proper clarifying shampoo after weeks of pomade or wax buildup, the amount of residue that comes out is genuinely eye-opening. The apple cider vinegar does the clarifying work cleanly and effectively, the ginseng and sage keep the scalp toned during the process, and the glycerin means hair doesn't feel punished after a deeper cleanse. Add it to your routine once or twice a week - slot it in on wash days when you want a full reset - and your daily shampoo will work better for it. The 473ml size makes it practical to keep on hand without running out quickly.
