RinseNo rinse

HairCovery Strengthening & Thickening Hair Serum is SeneGence’s pick for hair that looks thin, weak or dull. It’s a light, ivory cream serum that goes on your scalp, not your ends, and you leave it in. SeneGence lists thinning, strength and shine as the concerns, and says it suits all hair types, including color-treated hair.

A dime-size amount every few days. A small habit that's easy to keep.

Using it is easy: a dime-size amount on the scalp, on wet or dry hair, every two to three days, with no rinsing. The key ingredients listed now are acetyl tetrapeptide-3, Defenscalp and Lecigel. SeneGence’s product notes also highlight SenePeptide, which it describes as helping boost keratin for stronger, fuller-looking hair. Like any scalp serum, it’s a steady habit, not an overnight fix.

At $65 for 2.9 fl oz it’s one of the pricier hair products, though a dime-size amount every few days goes a long way. Honest note: sudden or patchy hair loss is a doctor question, not a serum question. If your scalp is dry and itchy rather than your hair looking thin, HairPlenish is the better fit.

Best for

Anyone who wants a no-rinse scalp serum for hair that looks thin, weak or dull.

Skip it if

Your main issue is a dry, itchy scalp. The HairPlenish Scalp & Hair Serum is aimed at that.

Wash, apply the detangler to your lengths, then part your hair and dot HairCovery onto the scalp. Because it works on wet or dry hair, you can also apply it in the evening on non-wash days. Dry shampoo on off days keeps roots fresh.

What’s in it, in plain words

  • Acetyl tetrapeptide-3: a peptide listed as one of the serum’s key ingredients.
  • Defenscalp: a scalp-focused ingredient SeneGence lists on the current formula.
  • Lecigel: a gelling ingredient that helps give the serum its light cream texture.
  • SenePeptide: a peptide complex SeneGence describes as helping boost keratin for stronger, fuller-looking lashes and hair.

My tips

Tip 1

Part your hair into sections and apply along each part, so the serum reaches your scalp, not just your hair.

Tip 2

Set a phone reminder for every third day; sticking with it matters more than using extra.

Tip 3

Massage it in with your fingertips for a minute so it spreads evenly instead of sitting in one spot.

HairCovery Serum FAQs

How do you use HairCovery?

Apply a dime-size amount to the scalp, on wet or dry hair, and don’t rinse it out. SeneGence’s directions say to use it every two to three days.

Is HairCovery safe for color-treated hair?

SeneGence says it’s suitable for all hair types, including color-treated hair. It goes on the scalp rather than your lengths, so it isn’t sitting on your colored ends.

Does HairCovery regrow hair?

SeneGence positions it for thin, weak or dull-looking hair, strength and shine. Results vary from person to person, and sudden or patchy hair loss is worth a visit to a doctor or dermatologist first.

What does HairCovery smell and feel like?

SeneGence describes it as a light, ivory cream serum with a floral-fruit scent. It’s a leave-in, so there’s nothing to rinse out afterward.

HairCovery or HairPlenish: which one?

HairCovery is for hair that looks thin, weak or dull. HairPlenish is for a dry, itchy, flaky scalp. Both are $65 for 2.9 fl oz, so choose by your main concern.
