When brows and lashes are still growing back after chemotherapy, a simple morning routine can feel uncertain. The good news: you don't need a complicated makeup plan to feel like yourself again. A small set of focused tools — a fine brow pencil, a shaping stencil, a gentle mascara — can rebuild definition one step at a time.
How we choose
This roundup highlights eight brow and lash products that support that process: ultra-slim pencils and a three-tip pen for hair-like strokes, reusable stencils for shape, a brow gel and fibre pencil for quick fill, a tubing mascara for easy removal, and a lash conditioner for ongoing care. Each product fills a specific role, so you can start with the one that matches where you are right now.
Our 8 Picks
Anastasia Beverly HillsBrow Wiz Ultra-Slim Precision Eyebrow Pencil | Precision Tip For Defined Brows, Natural Hair-Like Finish, High-Pigment, Long-Lasting Formula, Built-In Spoolie
What it is
An ultra-slim retractable eyebrow pencil with a built-in spoolie for drawing fine, hair-like brow strokes.
Why it's worth it
The 1mm tip allows you to build definition in small, controlled strokes, which suits brows that are sparse or growing back in patches. Its dry wax-and-pigment formula is buildable, so the first pass can stay light and natural. ABH states the formula is long-lasting, which is useful if you want to apply once and not worry about it fading.
Caveat
It is a pencil rather than a full brow product, so very bare brows may require extra layers or a second brow product to look fuller.
BenefitBrow Microfilling Pen #5 Deep Brown, 0.02 Ounce
What it is
A three-tipped brow pen that draws sheer, hair-like strokes to mimic the look of microblading.
Why it's worth it
The three-prong tip creates several fine lines in a single stroke, which is a good fit for covering larger bare brow areas more quickly than a single-tip pencil. The tint is described on the listing as buildable, so you can layer it gradually for more depth. Benefit states the formula is waterproof, sweat-proof and smudge-proof for 24 hours, which helps when you want to set brows and leave them.
Caveat
Because the finish is sheer, it may take a few layers to create stronger definition.
NYX PROFESSIONAL MAKEUPMicro Brow Pencil, Precise Eyebrow Pencil - Taupe
What it is
A retractable micro brow pencil with an ultra-slim tip and a spoolie for filling and blending eyebrows.
Why it's worth it
At around $11, it is a low-cost way to experiment with micro pencil drawing before moving to a pricier brow tool. The extra-fine tip is designed to create the look of individual hairs, which suits nearly bare brows where you need believable texture. NYX states this formula is vegan and waterproof, offering durability without a luxury price.
Caveat
The very fine tip means filling an entirely bare brow can take more strokes than a broader pencil or pen.
Anastasia Beverly HillsBrow Stencils Golden Ratio Shaping Guides Set | Patented Golden Ratio Design, 5 Shapes For All Faces, Achieve Perfect Symmetry, Durable & Easy To Clean
What it is
A set of five reusable brow stencils in different arch shapes for guiding powder or pencil application.
Why it's worth it
For someone who is not sure where a brow should start, arch, or end, the stencils provide a template that removes the guesswork. The five shapes let you compare different curves and choose one that suits your face. ABH says the flexible plastic is easy to wipe clean, so it can be reused throughout regrowth without getting damaged.
Caveat
The stencils are a shaping aid only, so they need to be used with a brow powder or pencil.
blincOriginal Tubing Mascara, Natural Look & Lengthening, Black
What it is
A tubing mascara that forms water-resistant tubes around each lash for a lengthened, natural finish.
Why it's worth it
Blinc says the tubing formula will not run, smudge, clump or flake, which makes it a good match for easily irritated eyes and low-maintenance wear. It is also a good fit for fragile new lashes because removal relies on warm water and gentle pressure rather than rubbing with remover. The formula is buildable, so you can keep the effect subtle or add layers.
Caveat
It is best suited to a natural lengthened look, not a dramatic volumised mascara effect.
RevitalashCosmetics, RevitaLash Advanced Sensitive Eyelash Conditioner 2.0 mL, Lash Enhancing Serum, Physician Developed & Cruelty-Free
What it is
An eyelash conditioning serum formulated for sensitive eyes, intended to support the look of healthier lashes.
Why it's worth it
This RevitaLash Advanced version is a good fit for an eye area that is easily irritated, since it is specifically formulated for sensitive eyes. The listing describes it as physician developed and hypoallergenic, and it is meant to condition lashes rather than add immediate colour. It works as a dedicated care step in a routine where lash makeup needs to be kept gentle.
Caveat
It will not give instant visible definition, so it is best paired with a brow or lash cosmetic for same-day polish.
GlossierBoy Brow Eyebrow Gel & Volumizing Pomade, Brown | Subtly Tinted, Defines, Conditions, Thickens & Shapes Eyebrows, Creamy Flexible Hold, No Flaking, Precision Application
What it is
A tinted brow gel-pomade with a mini brush that shapes, conditions and softly fills brows.
Why it's worth it
Glossier Boy Brow combines grooming and tinting in one step, which suits a quick routine. The listing describes a creamy flexible hold with no flaking, so brows stay in place without a stiff finish. The precision mini brush is designed to coat even fine hairs, making it a good fit for brows that are short or uneven during regrowth.
Caveat
The finish is soft and groomed rather than sharply defined, so it may not be enough on its own for completely bare brows.
RimmelBrow This Way Fibre Pencil, Medium Brown, 0.05 Ounce (1 count)
What it is
An eyebrow pencil with integrated fibres that adds colour and textural fill to sparse areas.
Why it's worth it
The fibres are designed to help fill in empty patches without requiring precise hair-by-hair strokes. Rimmel states the fibres help reduce the appearance of sparse areas, which is a good fit for early regrowth when brows are uneven. It is also the most affordable pick in this roundup, so it is easy to try without much commitment.
Caveat
It does not offer the same precision as a fine-tip pen, so defining a sharp arch may take extra care.

Takeaway
No single routine fits every regrowth stage. This roundup pairs precision drawing tools for brows, stencils for shape support, gels and fibre pencils for quick fill, a tubing mascara for gentle definition, and a conditioner for ongoing care. Pick one product that addresses today's concern and add from there.
