Is this the clients first ever tint treatment or have they had it done elsewhere before? You could always ask what theyve had done perviously. If it is their first treatment then personally I would go for a brown tint with a bit of the grey tint mixed in depending on the clients natural colouring (pale skin light brown or a darker colouring a darker brown with less of the grey tint mixed in).
You could always mix it and let the client tell you what they think.
Yes agree with above. Ask her what she wants to achieve from the treatment i.e something subtle. The older ladies with grey hair that I have had as clients ive always used brown. Obviously with the brows you can leave it on for a very short amount of time and reapply if needs be. The client will appreciate that you are concerned about getting it right, then obviously make a note for next time.
I would mix 3 quarter light brown with a quarter grey, or half & half, apply on to the first eyebrow, take straight off, then to the second eyebrow take straight off, show the client, if she wants darker, repeat.
With the eyelash tint, ask her what colour mascara she uses, does she want them dark - black, very dark - blue black, natural - brown? x
That's why i like Refectocil. You get a light brown, brown and chestnut brown so get a good range. I've never actually used the grey tint.
Grey hairs are quite coarse so you could go over them again if the tint doesn't cover them the first time
The brows will be the biggest challenge because grey hairs are a nightmare to cover and nine times out of ten your lady will say she doesn't want to go too dark but she wants the greys covered up(obviously)This poses a challenge because ideally we would pop the tint on the brows for 7 mins and leave to develope and cover the greys,however this will give an unatural,too dark, block colour.
I would do a thorough consultation,then if for example the client wanted brown eyebrows,I would tint the brows,take off,then reapply until desired effect,then only apply the tint to the grey hairs,this way you ensure not to go too dark BUT that the greys are covered,It can be time consuming so I would allow for a bit of extra time booked out.
I always advise that it's better to go a little darker initially because eyebrows do have a tendancy to fade relatively quickly,especially if going somewhere hot or swimming in chlorinated baths a lot.
Blue mixed with black Combinal tint is the darkest and a lot of ladies like to have very dark lashes,though again a lot like a more subtle look so I would go black brown unless client wants very light(very rare)in which case go for plain brown.
