Somewhere between your fourth stress-induced hair shed and that cruel bathroom lighting, you start to wonder: Is this just what happens now? But then your friend — the one who wears slip dresses in winter and gets regular facials “for lymphatic reasons” — casually mentions Amazon’s Big Spring Sale.
“It’s a system,” she says. “You have to do all three steps.” First, the shampoo detoxes your scalp, clearing out follicle-clogging buildup. Then comes the conditioner — lightweight but also strengthening. And finally, the treatment: a leave-in foam that targets your scalp with tingling, minty vengeance. She swears her hairline stopped retreating after two weeks. I believe her because her ponytail has been looking extra full (read: smug) lately.
The best part? This isn’t one of those placebo-effect, influencer-hyped products that only work on people genetically blessed with thick strands to begin with. It’s clinical. It’s trusted by pros. And it’s now half off — making it an actual bargain in the world of $75 scalp serums and $400 laser caps. Don’t wait for more hair to fall before taking action.
Nioxin Scalp + Hair Thickening System Kit
The Nioxin System 2 Hair Care Kit includes three full-size products: the Cleanser Shampoo (deep-cleans your scalp and removes sebum buildup), Scalp Therapy Conditioner (hydrates and strengthens thinning hair), and Scalp & Hair Treatment (a leave-in foam that supports regrowth and thicker strands). Designed for natural hair with progressed thinning. Dermatologist-tested, color-safe, and currently 50% off on Amazon.

Your Prime Big Deal Days FAQs, answered
What is Prime Big Deal Days?
This annual Amazon sale — which we like to call October Prime Day — is similar to the well-known July event: it’s a two-day blow out shopping event with deep discounts on bestsellers and everyday essentials. But the timing of this sale makes all the difference; shoppers can also score pre-Black Friday deals on top-rated toys and sell-out-risk gifts before the holiday rush.
Is Prime Big Deal Days over?
Technically, Prime Big Deal Days 2025 ended on Wednesday October 8 at 11:59 p.m. PT. But fortunately for professional procrastinators (you know who you are), Amazon extended tons of the best deals of the sale, so Prime members can continue to reap discounts.
Do you have to be an Amazon Prime member to shop?
Prime Big Deal Days is a member-exclusive sale event. Interested shoppers can try Prime, and its many benefits, with no strings attached.
Prime Day vs. Prime Big Deal Days: What’s the difference?
Already familiar with July Prime Day? Then you’ll love Amazon’s fall version! Like its summer spectacular sale, Amazon’s Prime Big Deal Days offers major discounts for 48 hours, but with a bigger focus on holiday gifts, toys and tech to shop ahead of Black Friday and Cyber Monday.
What are the best deals?
From reporting on Amazon sales for years, we can tell you for certain that October Prime Day is the ideal period to Amazon best-sellers.
Is it worth it?
We certainly think so! October Prime Day is a great chance to score Black Friday-worthy deals on thousands of best-sellers, including everything from big-ticket tech to Post reader-favorite trash bags. Our team diligently sorts through all the offers to find you the very best items to grab on sale.
When is the next Prime Day?
Already wondering when Amazon’s next Prime Day is? Prime Day takes place in July each year, so it’s safe to assume it will take place in mid-July 2026 — similar to previous years. Can’t wait to shop more Amazon deals? Look out for Amazon’s Black Friday sales to kick off the holiday season in November.
