HairPlenish Scalp & Hair Serum is the dry-scalp member of SeneGence’s three hair serums. It’s aimed at a scalp that’s dry, itchy or flaky, and it’s built on moisture: peptides, Aquaxyl, Botanimoist and Hydromanil. If your scalp feels tight in winter or after lots of hot water and heat styling, this is the one of the three to look at.
For the scalp that feels tight and itchy by the end of a long winter.
The trick with flakes is knowing why you have them. Dry-scalp flakes and oily-scalp flakes can look alike but want opposite things. HairPlenish is for dryness. If your scalp is oily, itchy and flaky, HairBalance Shampoo and the HairBalance Scalp & Hair Serum are aimed there. And flaking that’s persistent, red or sore is worth showing a doctor.
At $65 for 2.9 fl oz it’s priced like the other two serums. It makes sense if a dry scalp is a real, recurring problem for you. If your worry is thinning rather than dryness, HairCovery Serum is the one aimed at strength and fuller-looking hair.
Best for
A dry, itchy or flaky scalp, especially one that’s worse in cold, dry weather.
Skip it if
Your scalp is oily. The HairBalance Scalp & Hair Serum is aimed at excess oil and buildup.

Where it fits in your shower routine
1Moisturizing Body Washbody2Conditioning Hair Detangler and Primerlengths3HairPlenish Serumyou are here
Keep the water warm rather than hot, since hot showers dry out skin and scalp alike. Use a gentle shampoo that isn’t made for oily hair, the sulfate-free body wash for your body, and the leave-in Detangler on your lengths. HairPlenish goes on the scalp last.
What’s in it, in plain words
- Peptides: SeneGence describes peptides as supporting the skin and collagen production; here they’re part of a scalp formula.
- Aquaxyl: a sugar complex SeneGence describes as supporting the skin barrier and moisture.
- Botanimoist and Hydromanil: moisture-focused ingredients SeneGence lists among the serum’s key actives.
My tips
Tip 1
Apply to a towel-dried scalp along several parts so the serum reaches skin, not just the hair on top.
Tip 2
Turn the water temperature down a notch on wash days; very hot water leaves a scalp feeling drier.
Tip 3
Go easy on dry shampoo while your scalp feels dry, since powders can make it feel tighter.
