How to Fix Eyelashes Growing in Different Directions

You can redirect lashes that grow down or sideways starting today with a lash spoolie, a light conditioning product, and a few minutes of consistent grooming. For most people, daily brushing and the right serum or oil routine will produce noticeable improvement within 4 to 6 weeks and meaningful change by the 8 to 12 week mark. The key is separating what you can fix cosmetically right now from what takes time to repair at the follicle level, and knowing when a misdirected lash has crossed from annoying to actually dangerous.

Why your lashes grow in the wrong direction in the first place

Lash direction is set by the angle and orientation of the hair follicle, specifically the dermal papilla and the germinal hair matrix at the root. If that follicle sits at an angle pointing inward or sideways, the lash growing out of it will follow that path regardless of what you do on the surface. This is why some people have lashes that naturally trend downward (especially common in certain eye shapes and ethnicities where follicle angle differs), while others have a few rogue lashes that shoot sideways no matter how many times they brush them up.

Beyond natural follicle geometry, the most common triggers for lashes suddenly growing in new directions are: repeated rubbing or tugging of the lash line, poor removal of extensions or strip lashes, and inflammation or scarring around the eyelid margin. Eyelash extensions in particular are associated with allergic blepharitis and other irritation that can distort the tissue around the lash root over time. When that tissue gets inflamed or scarred, the follicle can shift angle and the lash starts growing abnormally. Chronic blepharitis (eyelid inflammation) is another well-documented cause. The lash growth cycle itself plays a role too: each lash goes through an anagen (growth) phase lasting roughly 4 to 10 weeks, a short catagen (transition) phase of about 15 days, and then a telogen (resting/shedding) phase before the whole thing restarts. A follicle disrupted by trauma or inflammation can restart its cycle in a slightly different orientation.

A more serious version of this problem is called trichiasis, a condition where lashes grow toward the eye rather than away from it. This isn't just a cosmetic annoyance because lashes rubbing the cornea and conjunctiva can cause abrasions, ulcers, and real corneal damage over time. If your misdirected lashes are actually touching your eyeball, that warrants professional attention, not just a better grooming routine.

What you can do right now to make lashes look better today

The fastest fix is mechanical: a clean spoolie brush and a light conditioning product can redirect most lashes within minutes. Here's how to approach it step by step.

1. Start with a clean, dry lash line. Remove any existing mascara or residue completely, since product buildup weighs lashes down and locks them into odd positions.
2. Warm a clean spoolie between your palms or use a slightly warm (not hot) spoolie. Warmth makes the lash shaft more pliable.
3. Brush from root to tip in the direction you want the lashes to go. For downward-growing lashes, brush upward and outward. For sideways lashes, redirect toward center or toward the outer corner depending on where they're straying.
4. Hold the spoolie in place at the tip for 5 to 10 seconds after each stroke. This isn't permanent reshaping, but it trains the lash position long enough to apply product.
5. Apply a thin coat of clear lash gel or a fiber mascara while holding the lashes in their redirected position. Clear lash gel is the most low-intervention option and won't add weight that drags lashes back down.
6. For guys or anyone avoiding makeup entirely, a tiny amount of aloe vera gel or a diluted castor oil blend applied with a spoolie creates a light hold without any visible product.

A heated lash curler can help with downward-growing lashes specifically. Apply gentle heat at the root, hold for 10 to 15 seconds, and release. This temporarily reshapes the lash shaft, though it won't change the follicle direction. Avoid clamping hard or pulling, especially if your lashes are already weakened from extensions or previous damage.

Lashes that grow down vs. lashes that grow sideways: the approach is different

These two problems feel similar but respond to slightly different strategies, and mixing them up leads to frustration.

Downward-growing lashes

Downward-growing lashes are often a follicle-angle issue, especially in people whose natural lid anatomy positions follicles angled toward the cheek. Grooming helps cosmetically, but the underlying direction won't change without addressing the follicle itself. Your best daily strategy: use an upward-curling motion with a spoolie every morning, apply a conditioning serum at the root at night (more on that below), and choose a lengthening or lifting mascara with a curved wand if you wear makeup. Downward-growing lashes are more common with certain natural lid and follicle angles, so your starting anatomy matters. Avoid heavy mascaras that add weight, since they pull downward-growing lashes even further down. The article on why lashes grow downward goes deeper into the follicle anatomy behind this pattern if you want the biology.

Sideways-growing lashes

Sideways lashes are more often caused by localized damage, a past stye, a healed blepharitis flare, or trauma from rubbing. They tend to be isolated: one or two lashes on one part of the lid rather than all lashes trending in one direction. For these, daily spoolie redirecting helps, but be realistic: if the follicle itself has been knocked off axis by scarring, consistent redirecting only manages the appearance, it doesn't fix the root. What you want to avoid is trimming rogue sideways lashes unless they're long enough to poke your eye, because a blunt-cut lash end is sharper and more irritating than a tapered natural tip. If the lash is genuinely causing irritation or poking the eye, clean removal (either by your own careful tweezing or by a professional) is safer than trimming.

What to avoid with both

• Aggressive rubbing or pulling to force lashes into position — this stresses the follicle and can worsen the direction on regrowth
• Applying extensions over already-misdirected lashes, which masks the problem while potentially making the underlying irritation worse
• Heavy waterproof mascara if your lashes are already weakened — removal requires more rubbing, which creates a damaging cycle
• Using a lash curler on lashes that are very short or fragile, since clamping can break them at the root

At-home conditioning and recovery to support healthier regrowth

Grooming redirects how lashes look right now. A consistent conditioning routine supports the follicle so the next lash cycle produces a stronger, better-oriented lash. These aren't the same goal, and it's worth being clear about that. You're working on two timelines simultaneously: the cosmetic fix (days to weeks) and the biological recovery (one to three full lash cycles, which can run 8 to 16 weeks total).

A simple nightly routine that actually works: after removing all eye makeup, use a clean spoolie to brush lashes gently from root to tip. Apply your chosen conditioning oil or serum along the upper lash line using a clean applicator. Don't apply to the waterline or inside the lid margin, just along the skin at the base of the lashes. Let it absorb while you sleep. Consistency matters more than the exact product, but the product you choose does matter.

Which ingredients actually help: castor oil, biotin, and serums

Let's be honest about what the evidence supports and what's mostly anecdotal, because the lash product space is full of marketing claims that outrun the science.

Castor oil is the most accessible starting point and has virtually no downside if applied carefully to the lash line. It won't change your follicle's direction, but it protects lashes during the recovery period, reduces breakage, and keeps lashes conditioned while the growth cycle does its work. Apply a small amount with a clean spoolie or cotton swab each night.

Prescription bimatoprost (Latisse) is the only FDA-approved topical treatment proven to extend lash growth. It works by prolonging the anagen phase. One important caution: apply it only to the upper eyelid margin using the sterile applicator it comes with. If the solution touches surrounding skin repeatedly, you can get unexpected hair growth in those areas. It can also cause eyelid skin darkening and, in rare cases, changes to iris pigmentation. These aren't reasons to avoid it if your doctor recommends it, but they're reasons to use it exactly as directed.

OTC serums with prostaglandin analogs carry similar but milder risks. They do work for some people, but they're worth reading the ingredient list on. If you see isopropyl cloprostenate or a similar prostaglandin analog in an OTC serum, treat it with the same care as a prescription product in terms of where you apply it.

How long this actually takes: a realistic timeline

Here's the honest version of the timeline most people need to hear before they give up or keep switching products:

The reason improvement takes this long is the lash growth cycle itself. The anagen phase for eyelashes runs roughly 4 to 10 weeks. That means a lash you're treating today might not even be in its active growth phase right now. You're essentially conditioning the scalp environment and waiting for the next generation of lashes to grow through it. This is genuinely how hair biology works, not a product disclaimer. Patience here is biological necessity, not just marketing language.

If you want to track progress, take a close-up photo of your lash line in natural light at the start and again at weeks 4, 8, and 12. Side-by-side comparisons are far more reliable than daily observation, which makes it hard to see gradual change.

When to stop DIY and see an eye professional

Most cases of lashes growing in different directions are cosmetic and manageable at home. But some situations cross into clinical territory, and knowing when you're in one of those situations matters.

See an eye doctor (ophthalmologist or optometrist) if you're experiencing any of the following:

• Persistent foreign body sensation in your eye — the feeling that something is scratching your eyeball even when nothing visible is there
• Redness, tearing, or light sensitivity that doesn't go away after a day or two
• A lash or lashes that are visibly touching your cornea or conjunctiva and can't be kept away with grooming
• Significant eyelid swelling, crusting, or discharge, which may signal blepharitis or infection
• Eye pain — this is never normal in a simple grooming situation
• Lash loss in patches or significant thinning that coincides with the misdirection (this may indicate an underlying condition rather than just follicle angle)
• Misdirection that appeared suddenly after trauma, a procedure, or an injury, especially if accompanied by scarring on the eyelid

The clinical diagnosis for lashes growing toward the eye is trichiasis. When a professional evaluates it, they may use a slit-lamp exam and fluorescein staining to check for corneal abrasion. Treatment options include removing the offending lashes, electrolysis to destroy the follicle so it doesn't regrow in the wrong direction, or more involved procedures for structural causes like epiblepharon. None of these are things to attempt at home.

If you've been using eyelash extensions and developed misdirected lashes alongside irritation or swelling, that combination is worth getting checked professionally, not just groomed away. Extensions are associated with allergic blepharitis and lid margin changes that can alter lash direction over time. An eye professional can evaluate whether there's ongoing inflammation that needs treatment before your DIY recovery routine can actually work.

The bottom line: use the grooming steps and conditioning routine to manage the cosmetic side of this today. Give a consistent serum or oil routine 8 to 12 weeks of honest effort. But if lashes are touching your eye, causing real pain, or the problem worsened after extensions or trauma, get professional eyes on it, the corneal abrasion risk from untreated trichiasis is not worth skipping the appointment.
